α Decay in extreme laser fields within a deformed Gamow-like model

In this study, the effect of extreme laser fields on the \(\alpha\) $\alpha$ decay process of ground-state even–even nuclei was investigated. Using the deformed Gamow-like model, we found that state-of-the-art lasers can cause a slight change in the \(\alpha\) $\alpha$ decay penetration probability of most nuclei. In addition, we studied the correlation between the rate of change of the \(\alpha\) $\alpha$ decay penetration probability and angle between the directions of the laser electric field and \(\alpha\) $\alpha$ particle emission for different nuclei. Based on this correlation, the average effect of extreme laser fields on the half-life of many nuclei with arbitrary \(\alpha\) $\alpha$ particle emission angles was calculated. The calculations show that the laser suppression and promotion effects on the \(\alpha\) $\alpha$ decay penetration probability of the nuclei population with completely random \(\alpha\) $\alpha$ particle-emission directions are not completely canceled. The remainder led to a change in the average penetration probability of the nuclei. Furthermore, the possibility of achieving a higher average rate of change by altering the spatial shape of the laser is explored. We conclude that circularly polarized lasers may be helpful in future experiments to achieve a more significant average rate of change of the \(\alpha\) $\alpha$ decay half-life of the nuclei population.
