Lifetime measurements of states in 110Pd

Abstract

Lifetimes of the 2 + 1, 4 + 1, 6 + 1, 2 + 2, 4 + 2, 0 + 2, 2 + 3 and 4 + 3 states in 110Pd have been measured using the recoil distance method. The measured lifetimes are compared with the E2 and M1 matrix elements measured in a separate Coulomb excitation experiment. The lifetime measurements agree, within the ≈5–10% experimental errors with the values obtained by Coulomb excitation. This agreement confirms the accuracy of the complicated analysis technique used to extract the matrix elements from the Coulomb excitation data. The measured E2 matrix elements can be understood within a macroscopic quadrupole collective model involving mixing of four quasi-rotational bands which have different shapes.
