Abstract :
Lifetime measurements with the Doppler shift attenuation method have been performed for the two superdeformed (SD) bands of 142Sm. The inferred transition quadrupole moments, Q0, are 11.7±0.1 eb for the yrast SD band and 13.2+0.8−0.7 eb for the excited SD band. These results are consistent with expectations from mean-field calculations, and indicate that the proposed additivity of contributions of individual orbitals to Q0 is valid for SD nuclei over an extended mass range in the vicinity of 152Dy.
