γ-Transitions Between Corresponding States in Mirror Nuclei

Abstract

It is shown that charge independence or charge symmetry give rise to the following relations connecting the strengths of $\gamma$-transitions between corresponding states in mirror nuclei: (a) the strengths of corresponding $E1\mathrm{}$ transitions are always equal; (b) the strengths of corresponding $M1\mathrm{}$ transitions should not differ in general by more than a factor 1.5; (c) for transitions with $\left|\Delta T\right|=1\mathrm{}$ the strengths of corresponding transitions of any multipolarity are equal.
