Properties of the low-lying negative parity states in 45Sc
J. Chevallier1, B. Haas1, N. Schulz1, M. Toulemonde1

The electromagnetic decays of the negative parity states in 45Sc up to an excitation energy of 2107 keV have been investigated via the 42Ca(α, pγ)45Sc reaction at a bombarding energy of 10.5 MeV. Reaction produced protons were detected in an annular silicon detector at an average angle of 171°. Gamma-ray spectra were measured with a Ge(Li) detector at angles 105° ≥ θ ≥ 0°. Spins and lifetimes of the levels as well as branching and mixing ratios of their decay γ-rays have been obtained from proton-gamma angular correlation measurements. Reduced electromagnetic transition matrix elements have been extracted for a number of observed transitions. Calculations based on the strong coupling model have been performed. The results are compared with experiment.
