Please note that only surfaces in the range 171 ≤ A ≤ 330 are available.
The reference to these calculated potential-energy surfaces
is HEAVY-ELEMENT FISSION BARRIERS P. Möller, A. J. Sierk, T. Ichikawa, A. Iwamoto,R. Bengtsson, H. Uhrenholt, and S. Åberg, Physical Review C 79 (2009) 064304. This publication presents only a few of the 5254 potential-energy surfaces we make available here. Please consult this reference for an in-depth discussion of the calculated potential-energy surfaces. Note in particular that for large prolate deformations with ε_{2} ≥ 0.5 the five-dimensional three-quadratic-surface parameterization is the most accurate. The surfaces here are particularly useful for establishing if superheavy nuclei have an oblate minimum that is stabilized with respect to fission by a high saddle in the axial-asymmetry plane. Figure 8 in the above reference, for ^{305}125 illustrates this possibility. |
