Abstract

The first measurements of DNN(0°) for (p→,n→) reactions at 295 MeV yield large negative values up to 50 MeV excitation for the Li6,11B,12C, C13(p→,n→) reactions, suggesting much stronger spin-flip strength than observed at lower bombarding energies. DWIA calculations using the Franey and Love (FL) 270 MeV interaction reproduce differential cross sections and DNN(0°) values, while the FL 325 MeV interaction yield DNN(0°) values less negative than the experimental values, suggesting that its exchange tensor part is too strong at large momentum transfer (Q3.4 fm-1).
