Observation of a double isobaric analog state in the reaction /sup 209/Bi(. pi. /sup +/,. pi. /sup -/)/sup 209/At

Journal Article · · Phys. Rev. Lett.; (United States)
Pion double charge exchange has been used to populate the double isobaric analog state in /sup 209/At with use of the neutron-rich target /sup 209/Bi. The data were obtained at an energy of 292 MeV and at an angle of 5/sup 0/, as the double-charge-eschange reaction mechanism has been shown to be dominated by analog transitions under these conditions in previous work on light nuclei. The measured cross section is found to be in good agreement with semiclassical predictions by Johnson.
