A=32五重态中的同位旋混合效应

Effects of isospin mixing in the A=32 quintet

Angelo Signoracci, B. Alex Brown

摘要:

对于A=32 T=2的五重态,我们对同位旋混合的三个相关方面提供了统一的理论描述:等压质量多重态方程中多于三项的必要性,同位旋禁戒质子衰变,以及对允许的费米β衰变的修正。我们第一次证明了实验中观察到的三种效应都可以追溯到一个共同的起源,即T=2态与T=1态的同位旋混合。

英文摘要:

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, and a correction to the allowed Fermi beta decay. We demonstrate for the first time 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.
