[en] An overview of many of the new insights extracted from γ,γ and γ-γ-γ coincidence studies of spontaneous fission of ²⁵²Cf and ²⁴²Up with large detector arrays at ORNL and Gammasphere will be presented. These include direct measurements of yields and neutron multiplicities from 0 to l0v for five correlated pairs, identification of a number of cold fission (cluster radioactivity) channels, identification of new structures and behaviors in many neutron-rich nuclei from ⁹⁴Sr to ¹⁶⁰Sm. From the yields of the correlated pairs, a new, second mode of SF is observed in the Mo-Ba pairs with much lower total kinetic energy. This mode goes via a hyperdeformed shape (3:1 axis ratio) for ¹⁴⁴Ba, ¹⁴⁵Ba, or ¹⁴⁶Ba. Calculations indicate a third minima in ²⁵²Cf at Β₃ ∼ 0.7 and Β₂ ∼ 0.9. The zero neutron cluster radioactivity yields for odd-odd Mo-Ba pairs are about four times larger than for the even-even ones in agreement with recent cluster radioactivity predictions. Identical bands are observed in ^98,100Sr, ^108,110Ru, ^144,146Ba, and ^152,154Nd nuclei and new types of identical bands in ^156,158,160Sm nuclei, and the first identical octupole bands. Octupole deformation is seen in N = 86, ¹⁴²Ba, ¹⁴⁴Ce and the new high spin octupole states to 19^- exhibit the first backbending and quenching of the static octupole strength as predicted by theory. Selected examples of the new physics being seen will be presented
