Abstract

The triaxial rotor model with independent inertia and electric quadrupole tensors is applied to the P3 term, P3=01||T(E2)||21 21||T(E2)||22 22||T(E2)||01, which is a standard measure of quadrupole interference in collective nuclei. It is shown that the model naturally explains nuclei with anomalous signs for their P3 terms. Measurements of Q(21) in multiple-step Coulomb excitation can be significantly dependent on the sign of this term. The example of Pt194 is considered.
