“…We found that eqs. (16) with the radii (13) reproduce the actual rigid body values (15) to within 2-3 %. Table 4 gives the deformation parameters (c, 12) and (pz, p4) and moments of inertia Bl(r = 0) for nuclei with 208 5 A 5 266 in their ground states, thus including the transition region between lead and actinides.…”

The transition levels at the top of the two 237 Np fission barriers were obtained for the first time by means of the so-called semimicroscopic combined method, which we have developed and implemented. To overcome the difficulties in dealing with large nuclear deformations, we used our developed BARRIER code, which calculates single-particle spectra in a deformed Woods-Saxon potential using a coordinate system based on Cassini ovaloids as nuclear shape parametrization. The results enabled us to describe the experimentally observed near-barrier photofission cross-section structures for 237 Np, as well as a subbarrier shelf, the latter being consistently interpreted in terms of the accumulation of levels at the top of the inner and outer double fission barrier of 237 Np.
