Study of the ~(19)O states via the (~7Li, ~7Be) reactionat 52 MeV

摘要

The ~(19)F(~7Li, ~7Be)~(19)O reaction at 52 MeV incident energy has been performed at INFNLNS in Catania using the MAGNEX large acceptance spectrometer. The use of an algebraic ray-reconstruction technique has allowed to extract the ~(19)O excitation energy spectrum and the experimental angular distributions. A theoretical analysis based on the Quasi-particle Random Phase Approximation has described the transitions to the 1p-lh states of the ~(19)O, in close agreement with the experimental cross sections without using any scaling factor.
