In this thesis, we will be concerned with the development of nucleon-nucleon cross sections appropriate for scattering of two nucleons in the nuclear medium and intended for applications in nuclear reactions. In particular, we will present an improved description of the Pauli blocking mechanism.The latter is an important effect which impacts the dynamics of two fermions in the many-body systems by preventing scattering into occupied states.
A novel characteristic of the present approach combines microscopic medium effects on the scattering amplitude with a Pauli blocking mechanism which is more appropriate for applications in ion-ion reaction models as compared to a previous approach. The effective in-medium cross section is found to be quite sensitive to the description of Pauli blocking in the final configurations.
