Total reaction cross section for p-Sm at E_p=65 MeV

The total reaction cross sections are integral properties of nuclei participating in the reaction. They play an important role in optical and statistical model calculations. Proton differential elastic scattering measurements are available for several stable isotopes and they provide an experimental basis for constraining optical model potentials (OMP). But, up to now, there are not enough experimental data on reaction cross sections to test the statistical model calculations even for stable isotopes, therefore predictions for unstable isotopes are uncertain. It is well known that there is a correlation between nuclear charge radii and reaction cross sections (σ_R). We can make use of this correlation to make a prediction of R for unstable isotopes with the knowledge of nuclear charge distributions and OMPs. In this abstract, we present the prediction of total reaction cross sections using the folding model approach
