Study of the 19O states via the (7Li,7Be) reaction at 52 MeV

The ¹⁹F(⁷Li,⁷Be)¹⁹O reaction at 52 MeV incident energy has been performed at INFN-LNS in Catania using the MAGNEX large acceptance spectrometer. The use of an algebraic ray-reconstruction technique has allowed to extract the ¹⁹O 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-1h states of the ¹⁹O, in close agreement with the experimental cross sections without using any scaling factor.
