Book Description
Direct measurements of yields and neutron multiplicities were made for Sr-Nd, Zr-Ce, Mo-Ba, Ru-Xe, and Pd-Te from[gamma]-ray coincidence studies in spontaneous fission of[sup 252]Cf. Strong enhancement of the 7-10[nu] emission channels is seen in the Mo-Ba data. Unfolding the Mo-Ba data revealed a new fission mode associated with the enhanced[nu] yields with much lower total kinetic energy going by[sup 108]Mo-[sup 144]Ba, [sup 107]Mo-[sup 145]Ba, and/or[sup 106]Mo-[sup 146]Ba. Analysis indicates one or more of[sup 144,145,146]Ba are hyperdeformed with 3:1 axis ratio. Theoretical calculations predict a third minimum in the PES for[sup 252]Cf with[beta][sub 2][approximately] 0.9 and[beta][sub 3][approximately] 0.7. Zero neutron emission channels, a new form of cluster radioactivity, are seen in 8 and 7 correlated pairs in SF of[sup 252]Cf and[sup 242]Pu, respectively, with the odd-odd zero neutron channel yields strongly enhanced as predicted for cluster radioactivity. New level structures and isotopes include new octupole deformations, identical bands and other structures.

Book Description
Coincident? rays from a 252Cf source were measured using an array of six segmented high-purity germanium (HPGe) Clover detectors each enclosed by 16 bismuth-germanate (BGO) detectors. The detectors were arranged in a cubic pattern around a 1?Ci 252Cf source to cover a large solid angle for?-ray measurement with a reasonable reconstruction of the multiplicity. Neutron multiplicity was determined in certain cases by identifying the prompt? rays from individual fission fragment pairs. Multiplicity distributions from previous experiments and theoretical models were convolved with the response function of the array and compared to the present results. These results suggest a?-ray multiplicity spectrum broader than previous measurements and models, and provide no evidence of correlation with neutron multiplicity.
