Abstract
Measurement of the spin-flip probability in the reaction at MeV yields values that are significantly smaller than those predicted by microscopic distorted-wave Born-approximation calculations. This is interpreted as direct evidence for the dominance of multistep processes in this reaction. Analysis of the data in terms of the spin-flip cross section (spin-flip probability times the differential cross section) yields an isoscalar strength for the which is significantly smaller than that predicted by random-phase-approximation wave functions.
