Pion single charge exchange in three body nuclei at intermediate energies
The purpose of this thesis is to present new experimental information about modifications to the pion-nucleon single charge exchange interaction, [pi][sup +]n [yields][pi][sup 0] p or [pi][sup [minus]] p [yields] [pi][sup 0]n, due to the presence of other nucleons. The results of two experimental studies of pion single charge exchange in the three nucleon system near the [triangle]-resonance are presented. Both of these experiments were performed at the Clinton P. Anderson Meson Physics Facility (LAMPF), a division of the Los Alamos National Laboratory. Each explored different aspects of pion single charge exchange in three body nuclei--[sup 3]He and [sup 3]H. Since the nuclear wavefunctions of the three nucleon systems are believed to be well understood, it should be possible to perform theoretical calculations of pion interactions with this system and compare their predictions with the experimental results
