Abstract
Precision Coulomb-excitation experiments using ions have been performed in the actinide region () by the observation of elastic and inelastically scattered projectiles using a split-pole magnetic spectrometer equipped with a position-sensitive proportional detector. 12 even- targets from to have been investigated and the reduced quadrupole matrix element, , and the reduced hexadecapole matrix element, , have been determined from the experimental excitation probabilities of the , , and states in the ground-state rotational bands. The values of range from 167 single-particle units for to essentially zero single-particle units for . Model-dependent deformation parameters, and , are extracted from the measured and transition moments for distributions of nuclear charge represented by deformed Fermi distributions and by a deformed homogeneous distribution.
