- Abstract
The neutron mid-shell silver nuclei exhibit anomalous ordering of the (7/2+, 9/2+) states. The two states are part of the πg-39/2 multiplet split under an unusually strong QQ interaction, leading to a rearrangement of the multiplet structure typical of the semi-magic Ag nuclei. To study the anomaly evolution with the neutron number, a systematic study of the electromagnetic transition rates was performed, showing that the M1 component of the 9/2+1 → 7/2+1 transition is typically hindered by at least two orders of magnitude with respect to the single-particle estimates, while the B(E2) component is enhanced. The experimental electromagnetic transition rates are systematically consistent with the three-hole valence-shell cluster and quadrupole vibrator coupling formalism developed in the 1970s.
