Abstrakt: We calculate the one-proton emission rate of nuclei near the proton drip line based on the WKB-approximation to determine Gamow’s penetrability factor. An analytical potential barrier parametrization is proposed, and the obtained results in the calculation are in good agreement with existing experimental data for one-proton emitters. In addition, the sum-energy distribution for two-proton emission from 45Fe is also determined. This decay mode has been observed by Miernik et al. [Phys. Rev. Lett. 99, 192501 (2007)], where the measured two-proton energy distribution for simultaneous emission has been also reported. We show that this energy distribution is well reproduced with the statistical assumption of two-proton emission being described by a product of the calculated individual one-proton emission rates.
