Generation of a database of differential cross sections for nuclear elastic scattering of $\alpha$ particles on nuclei

The general-purpose code for the simulation of radiation transport FLUKA accounts for the elastic scattering of charged projectiles on the screened electrostatic potential of target atoms. However, no dedicated model for the nuclear elastic scattering of ions heavier than the proton is implemented. A prospective study has been carried out to examine the extent to which nuclear elastic scattering of alpha particles can be systematically modelled. In this work we have examined an effective optical potential model for the alpha-nucleus interaction, we have numerically solved the radial Schrodinger equation and we have evaluated the differential cross section for elastic scattering (DCES) using the partial-wave method. A preliminary database of DCES has been generated for alpha particles of up to 400 MeV on targets ranging from 12C to 209Bi for the sampling of nuclear elastic scattering events
