Abstract

Differential cross sections and analyzing powers for the (p7,π+) reaction at Tp=250, 354, and 489 MeV leading to three excited states of Li8 are presented and are compared with previously published 200 MeV data. The differential cross sections at constant four-momentum transfer for two of the states exhibit an enhancement at approximately the Δ1232 invariant mass, and shapes of the analyzing power angular distributions for these states exhibit a characteristic ppdπ+ signature. Quite different dependences are observed for the third state.
