We have determined the branching ratio for single charge exchange using stopped negative pions on $\sp{115}$In, $\sp{45}$Sc, $\sp{32}$S, $\sp{31}$P, $\sp{27}$Al, $CH\sb2$. The experiment was done at the LEP channel at LAMPF. Negative pions at $50MeV$ were slowed down in a graphite degrader and brought to rest in the target nuclei. The neutral pions that comes from single charge exchange, decays into two gamma rays, which are then detected using the LAMPF $\pi\sp0$ spectrometer. The measured branching ratios are discussed within the framework of the simple shell model. The discussion of the observed branching ratios require consideration of angular momentum, parity, and energy. These results will allow theorists to determine the strength of the isovector pion-nucleon interaction in nuclei. This information can possibly be used to determine the origin of the large repulsion of the s-wave isoscalar pion-nucleon interaction in nuclei. / Source: Dissertation Abstracts International, Volume: 51-02, Section: B, page: 0811. / Major Professor: Hans S.
