The low excited states of Cr/sup 52/ are irvestigated, by studying the decay of Mn/sup 52/ with scintillation spectrometers and a double-focusing beta- ray spectrometer. In addition to three strong lines at 0.74, 0.94, and 1.43 Mev, a number of weak transitions are observed, which require the addition of level at 3.614 Mev, and which yield information on the spins and parities of the various levels. The following gamma rays are observed: 1.434 Mev (100%), 1.332 Mev Mev (0.9%), in addition to several weaker and more uncertain lines. A decay scheme is constructed that consists of levels at 1.434 Mev (2+), 2.369 Mev (4+), 2.648 Mev, 2.766 Mev (4+), 3.112 Mev (6+), 3.161 Mev (1,2,3), 3.614 Mev (5+, 6+), and 3.832 Mev (5+, 6+). A comparison is made between the experimentally determined level structure and theoretical calculations. Mn/sup 52/ is present in the Mn/ sup 52/. The energy of the Mn/sup 54/ gamma transition is determined to be 834.9 plus or minus 1.1 kev. (auth)
