Population of f472 states in the 41Ca(α, p)44Sc reaction

Abstract Angular distributions have been measured for the 41 Ca (α, p ) 44 Sc reaction at a bombarding energy of 25 MeV. The emerging protons have been analysed with a magnetic spectrograph and recorded in photographic emulsions. Angular distributions for the 40 Ca (α, p ) 43 Sc reaction have been measured with Si(Li) detectors both for normalisation of the 41 Ca (α, p ) 44 Sc cross sections and to test the optical potential used in the DWBA description of the ( α , p) reaction. Only positive parity states are observed below 1.6 MeV of excitation energy. The spectroscopic factors for these states have been calculated in a semi-microscopic model employing the f 4 7 2 model wave functions of McCullen, Bayman and Zamick. Also the spectator description is discussed at some length.
