Abstract：
A new rotational band has been observed in ) ¹⁶⁷Lu by ¹⁵²Sm( ¹⁹F,4n) ¹⁶⁷Lu reaction.The high spin transition energier of the new band are almost identical to the triaxial superdeformed bands recently discovered in ¹⁶³Lu and ¹⁶⁵Lu.This new band and the [660] band ¹⁷¹Ta are assigned as triaxical superdeformed bands by total routhian surface calculations based on cranked shell model.The formation mechanism of the superdeformed triaxial band in this region is discussed.
