(. pi. /sup +/,pp) and (. pi. /sup +/,pd) reactions in the lithium isotopes

Thesis/Dissertation ·
OSTI ID:5793985
The (..pi../sup +/,pp) and (..pi../sup +/,pd) reactions in /sup 6/Li and /sup 7/Li have been studied at T/sub ..pi../ = 59.5 MeV with high resolution. For the (..pi../sup +/,pp) reaction the first triple-differential cross sections are presented. The data are fitted to a T-matrix and are compared to the ..pi../sup +/d ..-->.. pp reaction. A model in which the pion is absorbed on a /sup 3/S/sub 1/ (pn) pair in the lithium nucleus is shown to describe many features of the data very well. A method for analyzing the (..pi../sup +/,pd) reaction has been developed and preliminary excitation spectra are presented.
