GAMMA-GAMMA ANGULAR CORRELATION AND INTENSITY MEASUREMENTS ON LOW ENERGY GAMMA RAYS IN THE DECAY OF Ce$sup 14$$sup 4$
The decay of Ce/sup 144/ was investigated using a gamma scintillation spectrometer and an automatic gamma-gamma directional correlation apparatus. The relative intensities of the gamma rays of Pr/sup 144/, 134 and 80 kev, and the 36 kev x ray were measured giving the following result 100: 33.4 plus or minus 1.0: 107.0 plus or minus 2.0. The result for the 80 kev gamma ray is in agreement with Rickok et al., and in disagreement with Geiger et al. A measurement was done of the gamma-gamma angular correlation of the 54-80 kev cascade in Pr 4. The measurement confirms the 1-spin assignment for the 134 kev level. In ND/sup 144/ was measured the angular correlation of the 1.49-0.69 Mev cascade. The result is in very good agreement with the previous measurements. (auth)
