摘要

<正> High-spin states of odd-odd 172Re has been studied, for the first time, by using 149Sm(27Al, 4n) 172Re reaction. The 27A1 beam was provided by the JAERI (Japan Atomic Energy Research Institute) tandem accelerator. The target was an enriched 149Sm metallic powder of 2.1 mg/cm2 thickness evaporated on to a 5.5 mg/cm2 Pb backing layer. A γ-ray detector array was used comprising 12 HPGe's with BGO anti-Compton
