Effects of isospin mixing in the A = 32 quintet.

For the A = 32, T = 2 quintet we provide a unified theoretical description for three related aspects of isospin mixing: the necessity of more than three terms in the isobaric mass multiplet equation, isospin-torbidden proton decay in 32Cl, and a correction to the allowed Fermi β+ decay of 32Ar. We demonstrate that all three effects observed in experiment can be traced to a common origin related to isospin mixing of the T = 2 states with T = 1 states. [ABSTRACT FROM AUTHOR]
