Abstract

After a long standing search of over 40 years, the simultaneous emission of two protons was discovered, An excited state in a light nuclei (¹⁸Ne), not a ground state, was identified as the first state to have such decay property. In this work, we review that discovery, discuss the concept of simultaneity and propose a simple analysis in terms of the shell structure of the nuclei involved. The analysis is generalized to all closed shells up to ⁴⁸Ca. It is predicted that no other nuclear state near closed shells, can decay by a pure simultaneous emission of two protons. The same analysis applied to the case of the simultaneous emission of two neutrons yielded the prediction of two sets of states in ¹⁴C and ¹⁸O with such property.
