Half-lives for One-proton Radioactivity within the Deformed Gamow-like Model
In this work,the Gamow-like model for calculating the one-proton radioactivity half-life is improved by introdu-cing the deformation of the nucleus.The calculations show that the deformed Gamow-like model can reproduce the experi-mental data better than the Gamow-like model.In addition,the reliability of the deformed Gamow-like model is confirmed by studying the linear relationship between the logarithmic form of the experimental half-life and the logarithmic form of the the-oretical penetration probability.As an application,the one-proton radioactivity half-life of the deformed nucleus is predicted using the deformed Gamow-like model,and the predictions are able to comply well with the Geiger-Nuttall law.Finally,by studying the relationship between the orbital angular momentum and the calculated half-life,the reference values of the orbital angular momentum of 109I and 131Eu are given to obtain a more accurate theoretical half-life for one-proton radioactivity.
