Calculation of the energy deposition in the targets from C to U irradiated with intermediate energy protons

Abstract

The energy deposition was calculated for the targets from carbon to uranium irradiated with intermediate energy protons with the help of different models incorporated in the MCNPX code package (Bertini, CEM and ISABEL) and with the help of the CASCADE/INPE code. The values obtained using the different models and codes are in a good agreement for all targets except uranium. The comparison with the available experimental data for the heat deposition for 0.8, 1.0 and 1.2 GeV protons has been performed. The good agreement is observed for copper, lead and bismuth target. The best result is obtained with the help of the ISABEL model. The systematic dependence of the heat deposition from atomic number of the target was investigated. The contribution of different particles and energy ranges in the heat deposition has been studied at the primary proton energies from 0.3 to 2.5 GeV.

Nuclear data for the cyclotron production of 117 Sb and 90 Nb

“…But in these models the different alpha, deuteron and proton exciton numbers are used in the pre-equilibrium GDH model calculations. In details, the other code model parameters can be found in reference [14]. In AL-ICE/ASH code, the hybrid and geometry dependent hybrid model (GDH) for pre-compound emissions and the Weisskopf-Ewing model for compound reactions are selected.…”

“…The excitation functions of 117-120 Sn, 90-92 Zr+xp, 115 Sn, 89 Y+α, and 117 Sn+xd reactions were calculated by using ALICE/91, ALICE/ASH (GDH Model & Hybrid Model) and TALYS-1.2 codes [12][13][14][15]. The codes were used simultaneously to increase the accuracy of calculations.…”

“…The calculational code TALYS can describe nuclear reactions induced by almost all the possible incident particles in the 1 keV-200 MeV energy range [14]. It is equipped with the ECIS-06 code [20] for optical model and direct reaction calculations.…”

Investigation of neutron skin effect with density dependence by using a new calculation method for initial exciton numbers on pre-equilibrium reactions

“…where N and Z are the neutron and proton numbers of the target nuclei, respectively. The ALICE/ASH code is an advanced and modified version of the ALICE codes for pre-equilibrium calculations [22]. The initial exciton numbers in the ALICE/ASH code calculations for proton-induced reactions are…”

“…where T is the kinetic energy of the projectile outside the nucleus and has units of MeV. In detail, all the other code model parameters can be found in Broeders et al [22].…”
