In the present work we systematically study the half-lives of proton radioactivity for 51 ≤ Z ≤ 83 nuclei based on the Gamow-like model with a screened electrostatic barrier. In this model there are two parameters while considering the screened electrostatic effect of Coulomb potential with the Hulthen potential, i.e. the effective nuclear radius parameter r 0 and the screening parameter a. The calculated results can reproduce the experimental data well. In addition, we extend this model to predict the proton radioactivity half-lives of 16 nu...
