New upper limits for β-delayed fission probabilities of 230,232Fr and 230,232,234Ac

The process of /3-delayed fission (/3DF) of 230,232Fr and 230,232,234Ac was studied in an experiment performed at the ISOLDE facility at CERN. As no fission fragments were observed for any of the nuclei investigated, upper limits for their /3DF probability (P/3DF) were determined. The experimental r...

As no fission fragments were observed for any of the nuclei investigated, upper limits for their /3DF probability (P/3DF) were determined. The experimental results were compared with theoretical calculations that were first benchmarked on 178,180Tl P/3DF experimental values. The P/3DF values were calculated using the code TALYS to which /3-strength functions obtained from the D1M Gogny parametrization and from the Skyrme functional SKO' were given as input together with fission paths obtained with BSkG3 and BSk14 models. Sensitivity studies of different /3-strength functions, and fission paths scaling on the P/3DF values were conducted, suggesting a stronger dependence of the P/3DF on the fission paths rather than on the /3-strength function used.
