The low-energy capture gamma-ray spectra of Eu/sup 152/ aud Eu/sup 154/ were examined up to an energy of 300 kev by the use of a scintillation spectrometer. Eu/sup 152/ was found to exhibit gamma lines at 81 plus or minus 4 kev and 92 plus or minus 3 kev while Eu/sup 154/ exhibited gamma lines at 75 plus or minus 3 kev and 91 plus or minus 3 kev. Coincidence measurements were made on a composite spectrum produced by thermal neutron capture in natural Eu/ sup 152/. The data are consistent with the interpretation that the Eu/sup 154/ lines are members of a rotational band while the Eu/sup 152/ lines are not. (auth)
