Predictions of total reaction cross sections for nucleon-nucleus scattering up to 300 MeV

Full text: Total reaction cross sections are predicted for nucleons scattering from various nuclei with incident energies to 300 MeV. Mass variations of those cross sections at selected energies are also specified. All predictions have been obtained from coordinate space optical potentials formed by full folding effective two-nucleon NN interactions with one body density matrix elements (OBDME) of the nuclear ground states. Good comparisons with data result when effective NN t matrices are used. Also we report on a simple functional form that gives a good representation of the total reaction cross sections for proton scattering from all nuclei with energies in the range 20 to 300 MeV, and which may find use in application programs involving, for example, spallation sources
