Abstract
Recent observations of the ΔI = 2 staggerings (or ΔI = 4 bifurcations) in several superdeformed (SD) bands [1–3] have shed light on the internal structure of the SD bands. The staggering parameter shows a systematic oscillation as a function of angular momentum I and its amplitudes increase in the typical cases [1, 2]. However, this anomaly is not always observed in every SD band, and there exist irregularities in the phase of oscillation. Recently, sthe staggering in 148Eu is observed, which shows an opposite sign to that in 149Gd [3]. It is quite desirable to find a mechanism and a common criterion for the occurence of the staggering.
