Reaction 48Ca(p,n) 48Sc from Esub(p) = 1.885 to 5.1 MeV

The total (p,n) reaction cross section for 48Ca has been measured as a function of proton energy in the energy range 1.885 to 5.100 MeV with an overall resolution of approx. 2 keV and in approx. 5 keV energy steps. The fluctuations in fine resolution data have been analysed to determine the average coherence width . The excitation function averaged over large energy intervals has been analyzed in terms of the optical model. The isobaric analogue resonances at Esup(p) approx. 1.95 and 4 MeV have been shape-analyzed to extract the proton partial width and the spectroscopic factor Ssub(n). A comparison of the gross structures observed in approx. 55 keV averaged excitation function with the predictions of Izumo's partial equilibrium model has also been made. (author)
