Total reaction cross sections are predicted for nucleons scattering from various nuclei. Projectile energies up to 300 MeV are considered. So also are mass variations of those cross sections at selected energies. All predictions have been obtained from coordinate space optical potentials formed by full folding effective two-nucleon $\mathrm{}\left(\mathrm{NN}\right)\mathrm{}$ interactions with one-body density matrix elements of the nuclear ground states. Good comparisons with data result when effective $\mathrm{NN}$ interactions defined by medium modification of free $\mathrm{NN}$ t matrices are used. Coupled with analyses of differential cross sections, these results are sensitive to details of the model ground states used to describe nuclei.
