Abstract

For a test of recent resonating-group calculations of 7Be the elastic-scattering data for 6Li(p, p0), described in the preceding paper, were analyzed with the phase-shift method. Both differential cross section and analyzing power are well described over the whole energy range of 1.6 MeV ⩽ Ep(lab) ⩽ 10 MeV. From the energy behaviour of the complex scattering phase shifts four broad overlapping resonance structures with total angular momentum 12, 32, 52 and negative parity have been deduced. These resonances, located at excitation energies in 7Be between 9 and 13 MeV have not been observed before, but have been predicted by the above mentioned calculations. The predicted resonance behaviour of the 2P32 phase shift was not confirmed by our analysis. Additionally a direct comparison of the data with the predictions of different resonating-group calculations is shown for some selected energies.
