Pion double charge exchange on Ca isotopes

A simple two-amplitude model introduced to relate pion double charge exchange on /sup 16/O and /sup 18/O is used to predict cross sections for /sup 42en-dash48/Ca, based solely on experimental data for /sup 40/Ca and simple predictions for double isobaric analog transitions. The presence of the ...

Zusammenfassung:	A simple two-amplitude model introduced to relate pion double charge exchange on /sup 16/O and /sup 18/O is used to predict cross sections for /sup 42en-dash48/Ca, based solely on experimental data for /sup 40/Ca and simple predictions for double isobaric analog transitions. The presence of the ''forbidden'' core component increases the expected /sup 42/Ca cross sections by a factor of 6 above the double isobaric analog transition prediction and changes the expected /sup 48/Ca//sup 42/Ca ratio by a factor of 4.5.
