Two-Proton Virtual Decay of the 19Mg Nucleus in the Superfluid Model

详细

The two-stage two-proton virtual nuclear decay theory and superfluid atomic nucleus model are used to investigate the total and partial widths, and the angular distributions of the emitted protons, for the two-proton diagonal virtual decay of the ground state of the \({}^{{19}}{\text{Mg}}\) nucleus into the ground state of the ¹⁷Ne nucleus. It is shown there is a set of parameters of the proton shell potential and superfluid proton–proton interaction for which the calculated total width of the two-proton decay of the \({}^{{19}}{\text{Mg}}\) nucleus agrees with its experimental value.
