Calculated fission barriers, ground-state masses, and particle separation energies for nuclei with 76 ≤ Z ≤ 100 and 140 ≤ N ≤ 184

Abstract

We calculate fission barriers and ground-state masses for 1125 nuclei with 76 ≤ Z ≤ 100 and 140 ≤ N ≤ 184. We use the macroscopic-microscopic method to calculate the energy as a function of elongation, necking, mass-asymmetric, and axially asymmetric shape coordinates. For the macroscopic model we use the droplet model with a 1973 set of parameters. The microscopic corrections are calculated by use of the modified oscillator model. The results are summarized in two tables. The first table gives, for each nucleus, the heights relative to the ground state of the saddle points and minima of the fission barriers and the corresponding values of the shape coordinates. The second table gives the ground-state mass excess, the maximum barrier height, neutron and proton separation energies, and alpha and beta Q-values.
