Neutron Flow in Ni＋Ni, Pb＋Ni and Pb＋Pb at 400 MeV/u

摘要

With the construction of the neutron wall for the external target experiment at CSR, it will be possible to detect high energy neutrons. A BUU model (Li Baoan, Phys. Rev. Lett. , 88, 19(2002)192 701.) is applied to simulate the. neutron flow in both symmetric (Ni+Ni,Pb+Pb) and asymmetric (Pb + Ni) systems.It is shown that, at the energy above iseveral hundreds of,MeV/u, the flow signals are very obvi-
