Angular distributions of pion double-charge-exchange (DCX) reactions at 50 MeV are reported for the ground-state (g.s.) and the double-isobaric-analog-state (DIAS) transitions on {sup 44}Ca. These distributions have similar shapes and magnitudes and are considerably more forward peaked than those of the lighter {ital T}=1 nuclei. The spectra at forward angles exhibit nearly exclusive excitation of the g.s. and DIAS. By using a formulation based on the shell model, the magnitude of the scattering amplitude {ital B} associated with nonanalog intermediate state transitions is extracted from the data.
