Abstract A superdeformed (SD) band consisting of 13 {gamma}-ray transitions has been observed in {sup 154}Er, an isotone of {sub 66}{sup 152}Dy. The experiment was performed using the {sup 118}Sn({sup 40}Ar,4{ital n}) reaction at {ital E}({sup 40}Ar)=185 MeV and the early implementation of GAMMASPHERE. This is an observation of a SD band in the {ital A}{approx}150 region with a proton number greater than 66. The J{sup (2)} moment of inertia of the band is constant above {h_bar}{omega}=0.45 MeV and shows a sharp rise below this value suggesting a paired band crossing. These results suggest that total Routhian surface calculations fail to accurately predict the deformation of the band.
