Fission properties for r-process nuclei

NUCLEAR STRUCTURE ^{250,252,254,256,258}No, ^{254,256,258,260}Rf, ^{258,260,262,264,266}Sg, ^264,266Hs, ²⁸⁴Cn, ²⁸⁸Fl; calculated half-lives and fission barriers with three different Skyrme parameterizations. Comparison with experimental data. Z=82-120, N=120-260; calculated fission barriers of even-even nuclei for four different Skyrme parameterizations and four theoretical mass models HFB-14, ETFSI, FRDM, and TF. Z=100-120, N=120-260; calculated fission half-lives for even-even nuclei using the Skyrme parameterizations, minimal lifetime plots for competing α decay and spontaneous fission. Comparison with experimental data. Z=84-120, N=120-260; calculated α-decay half-lives using the Q(α) values and the semi empirical Viola-Seaborg formula. Z=96-108, N=180-206; calculated difference of ground state energies and fission barriers between reflection symmetric and asymmetric configurations with the Skyrme parameterization, comparison of symmetric and asymmetric fission barriers and half-lives. ^286,294Rf; calculated PES for symmetric and asymmetric shapes with the Skyrme parameterization.
