摘要：

The elastic scattering of protons on Be-7 has been measured in the energy region from 1-3.3 MeV via the thick-target technique. The data conclusively demonstrate the existence of it 2 state at an excitation energy of approximately 3.5 MeV in B-8. and rule out a predicted 1(+) state near 1.4 MeV, The relevance of these results for the Be-7 (p, gamma) reaction, of interest in solar neutrino physics, is discussed.
