Interference effects in pion double charge exchange

Pion double charge exchange (..pi../sup +/,..pi../sup -/) has been measured using targets of /sup 16/O and /sup 18/O from 80 to 292 MeV at a laboratory angle of 5/sup 0/. The magnitude and energy dependence of the cross section for the double-analog transition is qualitatively described in terms of...

Beschreibung
Zusammenfassung:	Pion double charge exchange (..pi../sup +/,..pi../sup -/) has been measured using targets of /sup 16/O and /sup 18/O from 80 to 292 MeV at a laboratory angle of 5/sup 0/. The magnitude and energy dependence of the cross section for the double-analog transition is qualitatively described in terms of a direct double-analog amplitude and a two-step nonanalog amplitude.
