Laser-assisted α decay of the deformed odd-A nuclei

In this study, we explore the impact of state-of-the-art laser fields on the alpha decay half-life of deformed ground-state odd-A nuclei within the proton number range of 52-107. The calculations show that the presence of a laser field modulates the alpha decay half-life by altering the alpha decay penetration probability within a limited range. Moreover, the variance in the penetration probability rate of change between even-odd and odd-even nuclei is investigated. Furthermore, we investigate the rate of change of the penetration probability for the same parent nucleus with different neutron numbers, based on the characteristics of the odd-A nucleus. We found that the influence of the laser field on the penetration probability is determined by both the shell effect and odd-even staggering. This research contributes to the understanding of nuanced interactions between laser fields and nuclear decay processes. Therefore, valuable insights for future experiments in laser-nuclear physics are attainable using this study.
