Proton radioactivity of ^241-251Db

In the line of stability, the excess protons still adequately bound to the nucleus with the nuclear forces, hence direct emission of proton is not possible. However, while beyond the line of stability the protons are no longer bound by the nuclear forces. In the present work amount of energy released during the proton decay, has been studied along with penetration probability, normalization factor and logarithmic half-lives in the heavy nuclei of ^241-251Db. The present work has been compared with the spontaneous fission and alpha decay. From the results it can be concluded that the heavy nuclei of ^241-251Db are having half-lives greater than the spontaneous fission and alpha decay. Hence, the heavy nuclei ^241-251Db is stable against the proton decay
