In-beam gamma-ray spectroscopy of 172Os

POSTER

Abstract

A 30Si beam was used for a test experiment at the WNSL facility. The production of the compound nucleus 174Os was achieved through complete fusion in a 100 $\mu $g/cm2 144Sm target at beam energy of 134MeV. Gamma-rays from residual nuclei were detected with the YRAST ball array consisting of 7 Compton-suppressed clover detectors. A number of Os isotopes, in particular 172Os were also detected. While the main goal of the experiment was the commissioning of a gas-filled detector, we present here data from in-beam gamma-ray spectroscopy.
