Abstract

The lifetime of the fourth excited state of<superscript>45</superscript>Sc, at an energy of 720 keV, was determined in a nuclear resonant scattering experiment. Gamma rays of the desired energy for the excitation of this level were obtained by Compton scattering of the 1173 and 1332 keV photons from a 4300 Ci radioactive<superscript>60</superscript>Co source. A value of (5.6±1.2) meV was found for the radiation width of the level, assuming a value of 5/2 for its spin. The corresponding mean lifetime is (0.12<subscript>-0.02</subscript><superscript>+0.04</superscript>) ps. An attempt was made to determine the spin of the level by means of angular distribution measurements.
