DECAY OF Pm$sup 14$$sup 8$
The radiations arising from the activities of Pm/sup 148/ produced by proton bombardment of Nd/sup 148/ (93% enriched) were studied by a coincidence scintillation spectrometer. Gamma rays at 560, 900, and 1460 kev are associated with the 4.2-day activity, while the gamma rays associated with the decay of the 46-day activity are 105, which 560 and 630 are the most intense and of equal intensity. Beta-gamma and gamma-gamma coincidence experiments show that the main levels in Sm/sup 148/ arising from the negaton decay of the 46-day Pm/sup 148/ are 560, 1190, group associated with this activity is 2330 kev which goes to the ground state of Sm/sup 148/. A tentative decay scheme is proposed for the 46-day Pm/sup 148/ activity. (auth)
