| Popis: |
A new type of high resolution pair spectrometer for medium energy photons has been used for studies of the exclusive ( p , γ ) and ( p , e + e − ) reactions on light nuclei in the energy region 100 to 200 MeV. From the current experiments we present angular distributions of the differential cross section for transitions to the ground state and first three excited states in 12 C. The distributions from the ground state and first excited state are compared with predictions from a microscopic continuum shell model calculation which uses a realistic finite-range effective interaction with tensor components. Based on preliminary data, the salient features of the ( p , γ ) reaction on 12 C and the ( p , e + e − ) reaction on 11 B are also discussed. |
