The intrinsic {ital E}2 matrix elements {l_angle}{ital K}=2{vert_bar}{ital E}2{vert_bar}{ital K}=0{r_angle} for 25 deformed nuclei, covering from neodymium to uranium, have been deduced from measured interband {ital E}2 matrix elements between the ground band and {gamma} band after correcting for the first-order angular momentum dependence of the coupling between the rotation and intrinsic motion. Fairly precise centroids for the triaxiality of the intrinsic {ital E}2 moments are obtained, and these correlate well with the triaxiality implied by the excitation energies. The strong correlation of the triaxiality derived from the {ital E}2 properties and level energies provides a quantitative measure of triaxial quadrupole deformation of the nuclear shape for these states. {copyright} {ital 1996 The American Physical Society.}
