The antisymmetrized molecular dynamics(AMD)1was used to simulate the 64 Ni+58 Ni reaction at 40 AMeV.Events with different impact parameter(b)were selected by detecting the Zmax(the maximumZnumber of the fragments in an event),which energy is larger than or equal with 20 MeV/u in the laboratory system,of the fragments.Then select the neutron and proton in theta angle from 60°to120°in center-of-mass.
