Abstract
An accurate measurement of the energy of a gamma transition from the 7.56-Mev level in O15 discloses that the transition takes place to the 5.19-Mev level in O15 rather than to the 5.25-Mev level. Another transition takes place through the 6.15-Mev level. The third known transition occurs through the 6.79-Mev level rather than through the 6.86-Mev level. The angular correlations of cascades from the 7.56-Mev level through the levels at 6.79 Mev, 6.15 Mev, and 5.19 Mev are measured. These results, combined with previous results on these levels, are consistent only with Jπ=3/2+ and 3/2-, respectively, for the 6.79-Mev and 6.15-Mev levels. For the 5.19-Mev level, the present results indicate J=1/2, but are consistent also with J=3/2, if a suitable mixing ratio of E2 to M1 radiation is chosen. The preferred assignments are all consistent with the shell-model predictions and with comparisons with the N15 level scheme. It is noted that the doublets near 5.2 Mev in O15 and N15 are reversed in order.
