Single proton radioactivity from Drip Line Nuclei

In this work, proton decay from drip line nuclei is discussed, Shanmugam?Kamalaharan model is used which consists of a cubic barrier in the pre scission region connected by a Coulomb plus Yukawa plus exponential potential for the post scission region. Since proton decay transition rates are extremely sensitive to the orbital angular momentum of the proton, a centrifugal barrier is added to the post scission potential. Without any adjustable parameters this model is shown to give proton emissions half lives which are in excellent agreement with the recent experimental data.
