摘要：

A superdeformed band of 15 transitions has been found in the Dy-155 nucleus. The measurement was performed with a backed target and the large deformation was inferred from the measured Doppler shifts, The new band displays an intensity pattern much different from typical superdeformed bands in this mass region. The dynamic moment of inertia is essentially identical to that of band 1 in Dy-153 and is somewhat larger than those of the yrast superdeformed bands in Dy-152,Dy-154, suggesting that the associated configuration has an additional N=7,j(15/2) intruder orbital occupied with respect to the Dy-154 core.
