The Mean

The mean lives of the first excited ~- and ~+ states at 808 and 1391 keV excitation energy in 47SC were measured using the recoil-distance method (RDM). The levels of interest were populated in the 44Ca(O(, py) reaction using 9 MeV 0( beams. The mean lives extracted from the p-y coincidence data were ,(808 keV, ~-) = 22� 5 ps and ,(1391 keV, ~+) = 13 �4 ps. These results are compared with similar prior measurements on other levels of interest in 47SC as well as with those in the other Sc isotopes, and are discussed in the light of the systematics displayed.

The Mean

The recoil-distance method was used to measure the mean lifetime of the [Formula: see text], 1612 keV level in 37Ar. The level was populated via the 34S(α,n)37Ar reaction at Eα = 7.9 MeV. The mean lifetime was found to be 6.47 ± 0.22 ns.

Mean Lifetimes

The 3/2+, 975 keV level in 25Mg and the 945 keV level in 25Al were populated in the 2H(24Mg,pγ)25Mg and 2H(24Mg,nγ)25Al reactions respectively and their mean lifetimes for gamma-ray decay were measured by the recoil-distance method. The mean lifetime of the 975 keV level in 25Mg is 14.6 ± 1.5 ps and that of the 945 keV level in 25Al is 6.2 ± 1.6 ps. Using previously measured branching and mixing ratios, the absolute M1 and E2 transition probabilities have been obtained and are compared with predictions of the unified model.
