Phys. Rev. Lett. 88, 152501 (2002) [4 pages]Quadrupole Moments of Highly Deformed Structures in the A∼135 Region: Probing the Single-Particle Motion in a Rotating PotentialReceived 29 October 2001; published 27 March 2002 The latest generation γ-ray detection system, GAMMASPHERE, coupled with the Microball charged-particle detector, has made possible a new class of nuclear lifetime measurement. For the first time differential lifetime measurements free from common systematic errors for over 15 different nuclei ( >30 rotational bands in various isotopes of Ce, Pr, Nd, Pm, and Sm) have been extracted at high spin within a single experiment. This comprehensive study establishes the effective single-particle transition quadrupole moments in the A∼135 light rare-earth region. Detailed comparisons are made with theoretical calculations using the self-consistent cranked mean-field theory which convincingly demonstrates the validity of the additivity of single-particle quadrupole moments in this mass region. © 2002 The American Physical Society URL:
