抄録

Two features, a slow slope and a sharp drop, in neutron-induced total nonelastic cross sections in Al27 and Pb208 are analyzed within the framework of an intranuclear cascade (INC) model. First, to reproduce the slow slope from 100 to 10 MeV, the original INC is generalized in two points; a method to construct the ground state of the target nucleus and a method of taking the effective two-body cross sections between two nucleons. Second, to analyze the origin of the sharp drop from 10 MeV to nearly 1 MeV, the INC is extended to include quantum effects which are originated from the existence of the discrete levels in the nuclear potential. It is shown that this extension leads to the sharp drops in the very low energy below around 10 MeV. It is concluded that the INC model can be extended to explain the sharp drops in addition to the slow slope in neutron-induced nonelastic cross sections for Al27 and Pb208 in the energy region from 100 MeV down to 1 MeV.
