Abstract.
The nuclear potential between proton and the daughter nuclei is calculated in the frame of the proximity potential with a new universal function. We obtained and analyzed the half-lives of proton radioactivity of the mother nuclei. By comparing to the experimental data and the other calculation results of ground and isomer states of proton emitters, it is found that the present calculation results can reproduce the order of magnitude of the experimental data well. It indicates that the proximity potential with a new universal function can estimate the half-life of proton radioactivity.
