Abstract

We have measured branching ratios for the isospin-nonconserving particle decays of the 15.1-MeV $T = \frac{3}{2}$ states in ${}^{13}N$ and ${}^{13}C$ to the (0.0, $0^{+}$ ) and (4.44, $2^{+}$ ) states of ${}^{12}C$ . By comparing ratios of reduced widths with the $0^{+}$ and $2^{+}$ states of ${}^{12}C$ for the mirror decays, we show that the form of the isospin impurity in the 15.1-MeV states depends on $T_{z}$ .
