ResumoHigh-precision lifetime measurements have been performed in superdeformed (SD) bands of 151,152Dy and 151Tb with the Doppler-shift attenuation method. Differences found in the quadrupole moments Q0 of the yrast SD bands are understood in terms of shape polarization effects by the high-N intruder orbitals. Q0 moments are also presented for three excited SD bands in 151Dy. Recent calculations can account for most of the observations.
