Experimental Fission BarriersFission barrier parameters recommended for the transthorium nuclei by V.M.Maslov [1] and for the preactinides by G.N.Smirenkin [2]. For nuclei with Z<80 the liquid drop barriers described by Sierk's code [3] are recommended with the addition of the ground-state shell corrections estimated by the Moeller-Nix (Segment 1) or the Mayer-Swiatecki (Segment 5) mass formulae.

Level Densities at Saddle Points Calculated within HFBCSNuclear level densities at the fission saddle points for some 2300 nuclei with 78 <= Z <= 120 included in the ETFSI compilation [1]. The fission barriers and saddle point deformations are determined within the Extended Thomas-Fermi plus Strutinsky Integral (ETFSI) method. For each saddle point, the single-particle level scheme is calculated consistently by the HF-BCS model constrained on the corresponding quadrupole, octupole and hexadecapole moments.
