The 1042-kev state in Cm /sup 244/, which is populated in the BETA decay of 10.1-hv Am/sup 244/, has previously been assigned (K,I pi ) = (6,6/sup +/ ). This assignment has now been corfirmed through an angular correlation measurement, and it was found that the 746-kev gamma ray is a mixture of 48% quadrupole (E2) and 54% dipole (M1). The half life of the 1042-kev state was determined by measurenrent of delayed coincidences between BETA particles and conversion electrons. The result is 34 plus or minus 2 ms. Comparison with the single particle estimate shows that the E2 transitions from the delayed state are hindered by factors of about 10/sup 10/. This reflects the fact that the transitions are four times forbidden in K. The relative transition probabilities for the E2's from the delayed state are shown to agree well with a recent theoretical estimate. (auth)
