Abstract

We present results of measurements of the forward-angle cross sections for pion double charge exchange on ${}^{40, 44}{Ca}$ to the nonanalog ground states of ${}^{40, 44}{Ti}$ at incident pion energies from 35 to 80 MeV. The data indicate that a substantial contribution to these cross sections arises from core polarization and/or cross-shell transitions.
