Comparison of Nuclear Mass Models in the Cross-Section Calculations from the Reaction 37Cl on 100Mo

This study investigates the effects of four nuclear mass models on the calculations for reaction cross-sections: Myers-Swiatecki-Lysekil; Myers liquid droplet; Groote-Hilf-Takahashi; and Seeger models. We calculate cross-sectional values for the decay of the compound nucleus, 137Pr* from the reaction: 37Cl on 100Mo, using all possible sequences for neutron, proton, and α-particle emission obtained with the Hauser-Feshbach formula. We present mass-distributions for Pr, Ce, and La nuclei in the A=128-134 range at beam energies of 130-180 MeV and also include calculations for the case of dual-targets. The addition of the Wigner term to three of the models is expressed in terms of a linear, empirical function relating the atomic mass to the reaction cross sections. (author)
