The gamma rays emitted from Tm/sup 171/ following the Er/sup 171/ beta decay have been measured with the twometer curved-crystal spectrometer and a semicircular beta-ray spectrometer, enabling a comparison of the nuclear levels and rotational parameters for the Tm/sup 171/ ground-state band with the corresponding levels and parameters of Tm/sup 169/. The measured gamma rays have the following energies in kev: 5.06 plus or minus 0.05, l2.40 plus or minus 0.05, lll.6a plus or minus 0.02, 1l6.69 plus or minus 0.03, 124.03 plus or minus 0.03, 2l0.62 plus or minus 0.l5, 284.9 plus or minus 0.7, 295.97 plus or minus rameters, a slight increase in the deformation of Tm/sup 171/ over that of Tm/sup 169/ is noted. The relatively large change in the decoupling parameter (a = -0.8563) for Tm/sup 171/ compared with that of Tm/sup 169/ cannot be accounted for entirely by the small change in nuclear deformation.
