Abstract

The (n,α) reactions on 147Sm and 149Sm have been investigated at neutron energies up to 200 eV. The life times with respect to alpha-decay have been obtained for thirteen excited states of 148Sm and 150Sm with Jπ = 4- and 3-. Calculations, made according to the statistical theory, of the probabilities of 4- → 2+ transitions in 150Sm are in good agreement with the experiments. The life times of nine 148Sm states are in the region of 0.2 to 4 ns. The life times of the 3- and 4- levels differ by an order of magnitude.
