Decay Characteristics of Neutron Excess Vanadium Nuclei

Neutron excess vanadium nuclei are investigated using a single-particle model. The model predicts that A = 65 – 80 neutron excess vanadium systems are bound and have half-lives in the range of 0.277 – 8.53 ms. Model results for these nuclei are about a factor of 2 to 3 smaller than the calculations summarized in the Japanese Nuclear Data Compilation. The model calculations include the alpha, beta, positron, electron capture, and spontaneous fission decay modes. Short lived decay modes involving neutron emission are not evaluated. Omission of these modes suggests that the model results could overestimate the half-lives of neutron excess vanadium nuclei.
