摘　　要：In the present work,a phenomenological one-parameter model(OPM)based on the WentzelKramers-Brillouin(WKB)theory is applied to study the favored one proton radioactivity(the orbital angular momentum l taken away by the emitted proton is equal to zero)half-lives.The calculated results can reproduce the experimental data well within a factor of~3.In addition,we extend the OPM to predict the half-lives of possible favored one proton radioactivity nuclei whose decay is energetically allowed or observed but not quantified in NUBASE2020.For comparison,a universal decay law of one proton radioactivity(UDLP)is also used.It is obviously found that our predicted results are close to the ones using UDLP.The predictions are helpful for searching for the new nuclides with favored one proton radioactivity.
