Phys. Rev. C 80, 055207 (2009) [12 pages]Differential cross sections of the charge-exchange reaction π-p→π0n in the momentum range from 103 to 178 MeV/cReceived 25 August 2009; published 20 November 2009 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. © 2009 The American Physical Society URL:
