摘要: We have recently constructed a model for exotic decay studies using cubic potential the overlapping region that is smoothly connected by Yukawa-plus-exponential after separation. In this model, zero-point vibration energy explicitly used without violating conservation and inertial mass coefficient made dependent on center of distance, but deformation effect has not been included. work, it taken into account in both parent daughter nuclei, keeping emitted nucleus always spherical. This applied to cases $^{14}\mathrm{C}$ $^{24}\mathrm{Ne}$ emissions also reported $^{26}\mathrm{Ne}$, $^{28,30}\mathrm{Mg}$, $^{34}\mathrm{Si}$ emissions. It found fragment (which very small above decays) lifetime negligible while plays an appreciable role calculations.
