β-Decay Measurements in the Vicinity of ⁷⁸Ni with the EURICA Setup

Abstract

In this proceeding we report on a recent experiment performed at RIKEN with the EURICA β-decay setup. Following a relativistic fission reaction of a 238 U beam on a Be target, nuclei in the vicinity of 78 Ni have been transported and identified in the BigRIPS and ZeroDegree spectrometers. The EURICA cluster detectors are surrounded by the Si array WAS3ABI, in order to allow β − γ coincidence measurements. Additionally, an array of LaBr 3 from the FATIMA collaboration has been used for fast-timing measurements. In this proceeding we show results from the half-life measurement of the 1259 keV transition in 70 Ni, populated following two different decay paths. The on-going analysis will result in the measurement of new half-lives and level schemes in several nuclear species.
