LEVEL SCHEME OF 93ZR

In order to confirm a prediction made by Talmi 5), the gamma rays following the beta decay of the 10.25 h fission product 93Y were measured using a Ge(Li) spectrometer. In addition, the two-dimensional Ge-NaI coincidence spectrum was observed and the level scheme of 93Zr was derived. The level scheme of 93Zr presented here generally agrees with the level scheme derived by Knight et al. 8), and with the levels obtained by Cohen and Chubinsky 9) except for a few minor changes and a more exact energy determination. A level at 1167.7 keV was tentatively established and it was suggested that this is the 9 2+ level predicted by Talmi 5). © 1969.
