Abstract

The value of the pairing gap of both protons and neutrons is zero essentially over the whole range of the rotational frequency where the (+,0)-superdeformed configuration of 152Dy has been observed. Pairing fluctuations give rise to a dynamic dealignment by about 5h {combining short solidus overlay}, and alters the frequency dependence of the angular momentum to make I(2)>I(1) at low frequencies, the difference becoming smaller as the angular momentum increases. These results indicate the important role played by dynamical pairing correlations in the superdeformed rotational band of 152Dy.
