This paper presents precision measurements of electromagnetic decay probabilities associated with electric dipole transitions in the prolate-deformed nucleus Re-183. The nucleus of interest was formed using the fusion evaporation reaction Hf-180(Li-7,4n)Re-183 at a beam energy of 30 MeV at the tandem acceleratorat the HH-IFIN Institute, Bucharest Romania. Coincident decay gamma rays from near-yrast cascades were detected using the combined HPGe-LaBr3 detector array ROSPHERE. The time differences between cascade gamma rays were measured using the LaBr3 detectors to determine the half-lives of the two lowest lying spin-parity 9/2(-) states at excitation energies of 496 and 617 key to be 5.65(5) and 2.08 (3) ns respectively. The deduced El transition rates from these two states are discussed in terms of the K-hindrance between the low-lying structures in this prolate-deformed nucleus. (C) 2016 Published by Elsevier Ltd.
