摘要：
Rare cold (zero neutron emission and low excitation energy) binary fission, cold alpha and Be-10-accompanied ternary fission and cold fission with two neutrons emitted at scission and new nuclear structure effects have been observed in the spontaneous fission of Cf-252. Evidence for stable octupole deformation in Ba-143,Ba-144,Ba-146 and La-145,La-147 are presented. The roles of rotation in both enhancing and quenching stable octupole deformation are observed. In La-145 one has a new class of shape coexistence with symmetric and asymmetric rotational bands.
