摘要：

Gamma-ray spectra of a 20-h Fm-255 source containing similar to1 mCi activity were measured with a 25% Ge detector and a low-energy photon spectrometer (LEPS). Gamma lines with intensities as low as 1.0 x 10(-6)% per 255Fm, decay were observed. Gamma-gamma coincidence spectra of a Fm-255 Sample were measured with the GAMMASPHERE array. A comparison of the gamma -ray spectrum gated by the Cf K alpha x-ray peak with the gamma -singles spectrum provided spins of the excited states in Cf-251. The gamma -ray data, in conjunction with previously measured Cf-250(d,p) reaction data, allowed us to characterize several single-particle and vibrational states above the N = 152 subshell gap.
