Abstract The lifetimes of the 235 keV, 2− state and 350 keV, 4+ state in44Sc have been measured via the44Ca(p, n)44Sc reaction with a pulsed proton beam. The time integral perturbed angular distribution technique with an external field was used to measure the precession angles of the 2− and 4+ states populated by the30Si(16O,pnγ)44Sc reaction. The following values for the mean-lives andg-factors were obtained: τ(2−)=8.83(33) ns, g(2−)=0.30(13) and τ(4+)=4.52(27)ns, g(4+)=0.90(12). The results for the 2− state support a rotational description of the negative parity states in44Sc. The magnetic moment of the 4+ state is compared to shell model predictions.
