The measured lifetimes are τ2+ = 103(10) ps, τ4+ = 22(13) ps, and τ6+ 10 ps for the 2+ 1 , 4+ 1 , and 6+ 1 levels, respectively. Palladium-114 was predicted to be the most deformed isotope of its isotopic chain, and spectroscopic studies have suggested it might also be a candidate nucleus for low-spin stable triaxiality. From the lifetimes measured in this work, reduced transition probabilities B(E2; J → J − 2) are calculated and compared with interacting boson model, projected shell model, and collective model calculations from the literature. The experimental ratio RB(E2) = B(E2; 4+ 1 → 2+ 1 )/B(E2; 2+ 1 → 0+ 1 ) = 0.80(42) is measured for the first time in 114Pd and compared with the known values RB(E2) in the palladium isotopic chain: the systematics suggest that, for N = 68, a transition from γ -unstable to a more rigid γ -deformed nuclear shape occurs.This work was financially supported by the Science and Technology Facility Council (STFC) Grants No. ST/L005840/1, No. ST/L005743/1, and No. ST/G000751/1.
