Description etenko 2004-02-18 10:22:11 CET 
Simulation of the slow neutrons absorption by scintillator containing Cadmium
or Gadolinium shows systematic arrears of the exitation energy (~150 keV for Cd
and ~ 300 keV for Gd). This is due to different type of the total energy
calculation for neutron + target and for residual neucleus in NeutronHPCapture
model. For target the method GetIonMass(A,Z) is used and for neucleus the method
G4NucleiProperties::GetNuclearMass(A,Z). Last one takes into account the correction
1.433e-5*MeV*pow(Z,2.39) for the residual neuclear mass, which gives exactly the
values pointed before. May be the method G4NucleiProperties::GetNuclearMass(A,Z)
should be used in both cases?
Sincerely Yours Alexander Etenko
