Results from the Analysis of Crystal Ball Meson Production Measurements at BNL

Abstract

The Crystal Ball spectrometer, with its nearly complete angular coverage, is an efficient detector of photon and neutron final states. While installed in the C6 beamline of the Alternating Gradient Synchrotron (AGS) of Brookhaven National Laboratory (BNL), this feature was used in a series of precise measurements of reactions with all-neutral final states. Here we concentrate on the analysis of data from the pion-induced reactions: pi- p --> gamma n, pi- p --> pi0 n, pi- p --> eta n, and pi- p --> pi0 pi0 n.
