# $pi$$sup -$-p ELASTIC SCATTERING AND SINGLE PION PRODUCTION AT 0.939 BEV/c (thesis)

## Abstract

An investigation of pi /sup -/-p elastic scattering and singlepion production nt 0.939 Bev/c is reported. Fivehundred and forty two-prong interactions in the 10-in. UCRL liquid-hydrogen bubble chamber were classified. Emphasis is given the methods used in the kinematic classification of events. The total cross section for pi /sup -/-p interactions is found to be 53.3 plus or minus 2.4 mb. The elastic-scattering cross section is 21.0 plus or minus 1.1 mb. The elastic differential cross section displays a narrow diffraction peak in the forward direction. In the centerof-mass system, 35.6% of the elastic events have pion scatters into the backward hemisphere. In single-pion production the ratio of the number of pi /sup +/ to pi /sup 0/ productions is 2.49. The momentum distributions of the charged particles do not correspond to the phase-space distributions predicted. (auth)
