摘要：

Six superdeformed (SD) bands have been observed in the nucleus Gd-148 using the gamma-spectrometer GASP. The structure of the observed SD bands is discussed within the concept of cranked-Strutinsky-type calculations including pairing interaction. For the configuration assignments two different parametrizations of the Woods-Saxon potential are compared. Five of the observed SD bands are described in terms of quasiparticle configurations, whereas one is suggested to have vibrational-like structure. From this data a Delta I=2 staggering in the rotational spectrum of the yrast SD band also has been observed.
