Probing the Isospin Dependent In-Medium Nucleon-Nucleon Cross Section by Nucleon Emissions

The effects of the symmetry potential and the isospin dependent in-medium nucleon-nucleon (NN) cross section on the number of proton(neutron) emissions N\(_p(N_n\)) are studied respectively within an isospin-dependent quantum molecular dynamics (IQMD) model. The isospin dependent in-medium NN cross...

Summary:The effects of the symmetry potential and the isospin dependent in-medium nucleon-nucleon (NN) cross section on the number of proton(neutron) emissions N\(_p(N_n\)) are studied respectively within an isospin-dependent quantum molecular dynamics (IQMD) model. The isospin dependent in-medium NN cross section is found to have a strong influence on N\(_p(N_n\)) but N\(_p(N_n\)) is not sensitive to the symmetry potential for the neutron-deficient colliding system at relatively high energies.We propose to make use of the N\(_p(N_n\)) as a probe to extract information on the isospin dependent in-medium NN cross section.
