Relativistic binary kinematics calculator.

This class calculates various useful characteristics of binary nuclear reactions. It is based on a Fortran programme by Jean-Luc Charvet (cibi.for).

It allows to calculate:

centre of mass recoil velocity and available energy
laboratory grazing angle of projectile and target
maximum laboratory scattering angles
Q-values
CM and laboratory Rutherford cross-sections for elastic scattering
CM and laboratory angles of ejectiles after elastic or inelastic scattering
reaction cross-sections from systematics
equilibrium charge states from systematics

The values are calculated using relativistic kinematics.

Setting up the calculation

There are 3 ways in which KV2Body can be used.

Note on use of KV2Body constructors.

The arguments used to define the different nuclei are of type (const KVNucleus&). This means that you can use either

(1) a normal KVNucleus object instantiated before calling the constructor:
        KVNucleus xe("129Xe", 50.); // 129Xe nucleus with 50MeV/A kinetic energy
        KVNucleus sn(50,119);       // 119Sn nucleus at rest

        KV2Body kin(xe, sn);        // define kinematics of 129Xe+119Sn@50AMeV collision
(2) a temporary KVNucleus object instantiated in the argument list:
        KV2Body kin(KVNucleus("129Xe", 50.), KVNucleus(50,119));        // define kinematics of 129Xe+119Sn@50AMeV collision
(3) a string giving the symbol and mass of the nucleus.
        KV2Body kin(KVNucleus("129Xe", 50.), "119Sn");        // define kinematics of 129Xe+119Sn@50AMeV collision
(4) [ONLY WITH C++11/ROOT6]: any KVNucleus constructor through uniform initialization:
        KV2Body kin({"129Xe", 50.}, {50,119});        // define kinematics of 129Xe+119Sn@50AMeV collision

a. Collision kinematics

Calculate kinematics for either elastic or inelastic A + B -> A + B collisions.

Either use the constructor with arguments to specify projectile and target, and optionally the dissipated/excitation energy, or the constructor which takes as single argument a formatted name for the colliding system defining projectile, target and beam energy:

   KV2Body(const KVNucleus& proj, const KVNucleus& targ, double Ediss = 0);
 
   KV2Body(const Char_t* systemname);

or use specific methods to define the entrance channel after using the default constructor (without arguments):

SetProjectile(const KVNucleus&);
SetProjectile(int Z, int A = 0);
SetTarget(const KVNucleus&);
SetTarget(int Z, int A = 0);
 
SetEDiss(double);         // dissipated/excitation energy
SetExcitEnergy(double);   // same as SetEDiss

b. Binary reaction kinematics

Calculate kinematics for A + B -> C + D reactions.

Either use one of the constructors shown above to define the entrance channel then use the method below to define the outgoing fragment, or use the specific constructor with arguments to specify projectile, target, outgoing fragment, and optionally the dissipated/excitation energy:

KV2Body(const KVNucleus& proj, const KVNucleus& targ, const KVNucleus& outgoing, double Ediss = 0);

or use specific methods as above to define the entrance channel after using the default constructor (without arguments):

SetOutgoing(const KVNucleus&);

KV2Body::SetOutgoing

void SetOutgoing(const KVNucleus &proj_out)

Definition: KV2Body.cpp:398

Note that the partner of the outgoing fragment in the exit channel is deduced from conservation laws.

c. Binary decay kinematics

Calculate kinematics for A -> C + D decays.

Define the compound nucleus and its excitation energy with the constructor

KV2Body(const KVNucleus& compound, double Exx = 0);

(if Exx is not given, the excitation energy of compound is used) and then define the decay channel with

SetOutgoing(const KVNucleus&);

Calculating and obtaining reaction information

Once the entrance channel (and, if necessary, the exit channel) is(are) defined, the kinematical calculation is carried out by:

CalculateKinematics();

KV2Body::CalculateKinematics

void CalculateKinematics()

Definition: KV2Body.cpp:678

For a general print-out of the reaction characteristics:

Print();
Print("lab");//laboratory scattering angles and energies
Print("ruth");//Rutherford scattering angles, energies and cross-sections

Examples: ExampleFilteredSimDataAnalysis.cpp, and ExampleINDRAAnalysis.cpp.

◆ KV2Body() [2/6]

KV2Body::KV2Body ( const Char_t * systemname )

Set up calculation defining entrance channel following this prescription:

[Projectile_Symbol]+[Target_Symbol]@[Incident_Energy]MeV/A [Projectile_Symbol]+[Target_Symbol]@[Incident_Energy]MeV/u [Projectile_Symbol]+[Target_Symbol]

Any spaces will be ignored.

Valid examples:

129Xe.nosp@m.+119.nosp@m.Sn@50.nosp@m..0Me.nosp@m.V/A 58Ni + 64Ni @ 32 MeV/u U+U@5MeV/A Ta+Zn

If the format is not respected, this object will be a zombie (IsZombie() returns kTRUE)

◆ KV2Body() [3/6]

KV2Body::KV2Body	(	const KVNucleus &	compound,
		double	Exx = `0.0`
	)

Set up kinematics of binary decay of compound nucleus.

The excitation energy of the CN (in MeV) is either given:

in the KVNucleus object itself (i.e. compound.GetExcitEnergy() gives the E* of CN)
or in the variable Exx: in this case any E* in the KVNucleus will be ignored
or by calling SetExcitEnergy or SetDissipatedEnergy after this constructor with the NEGATIVE E*

Usage:

KVNucleus CN("204Pb");
CN.SetExcitEnergy(1.5*CN.GetA());
KV2Body CNdecay(CN);
 
 or: KV2Body CNdecay("204Pb", 1.5*204);
* or: KV2Body CNdecay("204Pb");
* CNdecay.SetExcitEnergy(-1.5*204);

Set up calculation of basic binary reaction for given projectile and target.

By default the dissipated energy Ediss is zero (elastic reaction).

Usage:

KV2Body reaction(KVNucleus("129Xe",50), "natSn");
 
// or with C++11 (ROOT6):
KV2Body reaction({"129Xe",50}, "natSn");

KV2Body::KV2Body	(	const KVNucleus &	proj,
		const KVNucleus &	targ,
		const KVNucleus &	outgoing,
		double	Ediss = `0.0`
	)

Set up calculation of basic binary reaction for given projectile and target with definition of exit channel (outgoing projectile- or target-like fragment).

By default the dissipated energy is zero (elastic reaction).

Any excitation energy of the outgoing fragment will be taken into account, e.g. for quasi-elastic scattering leaving the target in an excited state.

Usage:

KV2Body reaction(KVNucleus("129Xe",50), "natSn", KVNucleus("24Mg",35));
 
// or with C++11 (ROOT6):
KV2Body reaction({"129Xe",50}, "natSn", {"24Mg",35});

◆ EqbmChargeState()

Double_t KV2Body::EqbmChargeState	(	Double_t *	t,
		Double_t *
	)

Calculate the mean charge state of the projectile after passage through the target, assuming that the equilibrium charge state distribution is achieved*. t[0] = energy of projectile after the target (in MeV/nucleon)

We use the empirical parameterization of Leon et al., At. Dat. and Nucl. Dat. Tab. 69, 217 (1998) developed for heavy ions in the GANIL energy range (it represents a fit to data measured using GANIL beams).

*N.B. Concerning equilibrium charge state distributions, it is not easy to know whether, for a given combination of projectile, projectile energy, target, and target thickness, the equilibrium distribution is reached or not. Here are some comments from the paper cited above which may give some guidelines:

"The energies available at the GANIL accelerator range from 24 to 95 MeV/u. Within this energy range, the equilibrium charge state is reached only for fairly thick targets (~1 mg/cm2 for C foils)."

"Mean Charge State as a Function of the Target Thickness A typical example of the variation of the mean charge as a function of the foil thickness is shown ... It is seen that the mean charge initially increases due to the ionization process. Then, the equilibrium state is reached at a certain thickness, the so-called equilibrium thickness, due to the equilibration of electron loss and capture processes. Finally, for foils thicker than the equilibrium thickness, the mean charge decreases due to the slowing down of the ions in matter leading to higher capture cross sections."

It should be noted that, according to the data published in this and other papers, the equilibrium thickness decreases with increasing atomic number of the target, and increases with increasing energy of the projectile.

private

Find at most two solutions x1 and x2 between xmin and xmax for which fonc->Eval(x) = val i.e. we use TF1::GetX for a function which may be (at most) double-valued in range (xmin, xmax) This is adapted to the case of the lab angle vs. CM angle of scattered particles. if fonc has a maximum between xmin and xmax, and if val < max, we look for x1 between xmin and the maximum, and x2 between the maximum and xmax. If not (single-valued function) we look for x1 between xmin and xmax. This method returns the number of roots found. If val > maximum of fonc between xmin and xmax, there is no solution: we return 0.
