“…Dashed lines show the calculation results of JQMD by the use of free NN elastic cross sections, i.e., without consideration of inmedium effects. Solid lines stand for the calculated results of JQMD with in-medium effect in target nuclei; the code adopts the modified NN elastic-scattering cross sections of Suetomi [8].…”

“…Results of INCE calculations have been compared with experimental data to reveal certain drawbacks in calculation codes. Ishibashi et al [6] showed that adoption of the in-medium effects [8] on NN cross sections in the Bertini INC calculation improves the agreement between the calculated results and experimental data in low energy neutron emission. Leray et al [7] indicated that the Cugnon INC model [9] provides better agreement with the data than that of Bertini, mainly because of nucleon-nucleon cross sections that take into consideration in-medium effects and improved treatment of angular distribution of NN → N⌬ and Pauli-blocking.…”

Particle production in nucleon induced reactions above 14 MeV with an intranuclear cascade model

“…The density-dependent in-medium cross sections of Li and Machleidt [48] have already been used with the INC model of Bertini [50]. The authors of Ref.…”

Probing the density dependence of the quantum molecular dynamics potential with spallation neutrons induced by 1.2 GeV protons on Al, Fe, Zr, and Pb

“…Recently, several laboratories have made an extended effort to measure neutron spallation data induced by intermediateenergy (≈1 GeV) proton-nucleus interaction [1][2][3][4] in order to establish a base for the testing and validation of spallation microscopic transport models [5][6][7][8][9][10][11][12]. These data are also important in several areas, e.g., accelerator shielding, transmutation of transuranic wastes by spallation reactions, and medical applications.…”

“…Two major microscopic approaches are frequently applied: the intranuclear cascade (INC) models [5,6], in which the nuclear reactions are assumed to proceed from a succession of nucleon-nucleon (NN) collisions, and the quantum molecular dynamics (QMD) models [7][8][9][10][11][12], which account for both the multiple NN-scattering picture and the features of the mean field dynamics [or nuclear matter equation of state (EOS) effects].…”
