Non-equilibrium nucleon spectra from reactions at intermediate energies.
A new exciton model of pre-equilibrium decay (Monte Carlo Pre-equilibrium) to compute spectra of multiparticle emission during an establishment of statistical equilibrium in the composite system is proposed. The MCP stage of the calculation was included into the standard scheme of the nucleon spectra calculation between the intranuclear cascade stage and statistical model stage. A systematic comparison of calculation results with experimental spectra of nucleons from (p,xn), (p,xp), (n,xn) and (n,xp) reactions in a wide projectile energy region from 10 up to 160 MeV for targets from (27)Al up to (209)Bi has been carried out. A short description of the MCP model and results obtained are presented.
