Title: Effects of isospin mixing in the A=32 quintet

Abstract

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-forbidden proton decay in {sup 32}Cl, and a correction to the allowed Fermi {beta}{sup +} decay of {sup 32}Ar. 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.
