Abstract

Double charge exchange cross sections for 50 MeV pions to double isobaric analog states in ⁴⁴Ca, ⁵⁶Fe, and ⁹³Nb 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 ⁹³Nb.
