Sammanfattning

Lifetimes of low-lying states in ⁷³Ga and ^70,72,74Zn were measured using the Recoil Distance Doppler Shift (RDDS) method. These nuclei were produced in deep-inelastic reactions in inverse kinematics with a ²⁰⁸Pb beam impinging on a ⁷⁶Ge target. Prompt γ rays were detected using the AGATA tracking array coupled to the VAMOS++ spectrometer. Lifetime of the 5/2^- state in ⁷³Ga, measured for the first time, provides additional evidence for the existence of a 1/2^-, 3/2^- ground-state doublet. The lifetimes of the 4⁺ states in ^70,72,74Zn were remeasured in an attempt to understand the discrepancies observed between earlier measurements. Our results are in agreement with those of previous plunger experiments.
