英文摘要:
A comprehensive analysis of the superdeformed bands observed near A approximate to 190 indicates that there exist systematic odd-even differences in the moments of inertia similar to that observed in normally deformed nuclei, which can be considered as compelling evidence for pairing and blocking effect in superdeformed nuclei. With increasing rotational frequency the odd-even differences become weaker and weaker due to the Coriolis anti-pairing effects. Particularly, the odd-even differences in the dynamic moments of inertia become obscure when ($) over bar h omega greater than or equal to 0.2 MeV, and in certain cases there emerges nearly identical value of J((2)) for some neighboring nuclei. However, the odd-even differences in the kinematic moments of inertia still remain to certain extent at the highest frequencies.
