Nuclear fission

A set of fission barriers and the corresponding nuclear level densities have been generated for various applications. Accurate level densities are prescribed within GSM for reactor physics studies. Since fission level densities and barrier parameters are strongly interdependent, the corresponding set of parameters for both the inner and outer fission barriers has also been provided. Some specific applications, such as accelerator-driven systems and stellar nucleosynthesis, require a knowledge of large numbers of fission barriers and level densities to estimate spontaneous as well as neutron-induced or β-delayed fission probabilities. Hence, the present compilation includes fission barriers for some 2301 nuclei with 78 ≤ Z ≤ 120 derived by means of the ETFSI method, and the corresponding level densities at both saddle-point deformations predicted by the microscopic model based on HFBCS single-particle properties.
