computeExcitationEnergyExcept()

G4double G4INCL::ProjectileRemnant::computeExcitationEnergyExcept

const

Compute the excitation energy when a nucleon is removed.

Compute the excitation energy of the projectile-like remnant as the difference between the initial and the present configuration. This follows the algorithm proposed by A. Boudard in INCL4.2-HI, as implemented in Geant4.

Returns
