Differential cross sections of the charge-exchange reactionπ−p→π0nin the momentum range from103to178MeV/c

Abstract

Measured values of the differential cross sections for pion-nucleon charge exchange, π−p→π0n, are presented for π− momenta of 103,112,120,130,139,152, and 178 MeV/c. Complete angular distributions were obtained by using the Crystal Ball detector at the Alternating Gradient Synchrotron at Brookhaven National Laboratory. Statistical uncertainties of the differential cross sections vary from 3 to 6% in the backward angle region and from 6 to about 20% in the forward region with the exception of the two most forward angles. The systematic uncertainties are estimated to be about 3% for all momenta.4 MoreReceived 25 August 2009DOI:https://doi.org/10.1103/PhysRevC.80.055207©2009 American Physical Society
