摘要

Superstrong static electric fields could deform Coulomb barriers between α clusters and daughter nuclei,and bring up the possibility of speeding up α decays.We adopt a simplified model for the spherical α emitter 212Po and study its responses to superstrong static electric fields.We find that superstrong electric fields with field strengths |E| ～ 0.1 MV/fm could turn the angular distribution of α emissions from isotropic to strongly anisotropic,and speed up α decays by more than one order of magnitude.We also study the influences of superstrong electric fields along the Po isotope chains,and discuss the implications of our studies on α decays in superstrong monochromatic laser fields.The study here might be helpful for future theoretical studies of α decay in realistic superstrong laser fields.
