Double charge exchange to the double isobaric analog state at T/sub. pi. /--292 MeV

Journal Article · · Phys. Rev. C; (United States)
Measurements of cross sections for the (..pi../sup +/,..pi../sup -/) reaction to the double isobaric analog state on targets of /sup 30/Si, /sup 34/S, /sup 44/Ca, /sup 50/Ti, /sup 51/V, /sup 52/Cr, and /sup 58/Ni at theta/sub lab/ = 5/sup 0/ and an incident pion kinetic energy of --292 MeV are presented. We also present limits for the cross section to the residual ground state for the four T>1 targets. The data are compared with a phenomenological two-amplitude model and with a two-amplitude model that uses seniority-zero shell-model wave functions. The latter model provides expressions for both ground state and double isobaric analog state cross sections.
