Abstract

The widths for one- and two-proton decay of the 1₂^- state in ¹⁸Ne are calculated. Shell-model wave functions are used to obtain the spectroscopic factors. The R-matrix theory of Barker which incorporates the final-state interaction between the two protons is used for the di-proton decay model. The calculated widths for both one- and two-proton decay are in qualitative agreement with experiment. We find that the decay width for sequential two-proton decay through the ghost of the 1/2⁺ bound state in ¹⁷F is comparable to the width of the direct di-proton decay.
