Residual np-interaction and mass predictions in transfermium region

Abstract

We study the consistency of local mass relation approach in its application to prediction of nuclear masses in the region of superheavy elements. Binding energy calculations are carried out for nuclei with A > 200 using formulas for evaluation of residual np-interaction. The results are found to be in good agreement with the experimental data AME2016. We also make predictions for characteristics of α-decay in isotopes Z = 101–106, N = 144–157.
