Differential cross sections for pion charge exchange on the proton at 27.5 MeV

Abstract

We have measured pion single charge exchange differential cross sections on the proton at 27.5 MeV incident {pi}{sup {minus}} kinetic energy in the center of momentum angular range between 0{degree} and 55{degree}. The extracted cross sections are compared with predictions of the standard pion-nucleon partial wave analysis and found to be in excellent agreement. {copyright} {ital 1998} {ital The American Physical Society}
