Charge exchange scattering near the N *(1510) and N *(1690) resonances

Abstract

This is a report on some preliminary results of an experiment (Calvelli et al. 1964; Bordner et al. 1965; Bulos et al. 1964 a, b ) performed at the Cosmotron to measure the total cross sections and the angular distributions in the charge exchange reaction π - + p → π 0 + n at eleven energies between 500 and 1150 MeV. The experiment was accomplished by a collaboration between groups of Brandeis, Brown and Harvard Universities and the Massachusetts Institute of Technology in U.S.A. and of Padua University in Italy.
