Abstract

Double charge exchange cross sections for 50 MeV pions to double isobaric analog states in Ca44, Fe56, and Nb93 were measured. The results indicate that the effective double charge exchange operator at this energy has a strong short-range component. In addition, evidence is presented tending to implicate isospin mixing as the mechanism for excitation of the analog of the antianalog in Nb93.
