Nuclear reactor physics and engineering

The γ radiation and neutrons emitted following the β decays of 24O, 25–27F, and 28−30Ne have been measured. The nuclides were produced in the quasifragmentation of a 2.8 GeV 36S beam, separated in-flight and identified through time-of-flight and energy-loss measurements. The ions were stopped in a silicon detector telescope, which was used to detect the β particles emitted in their subsequent radioactive decay. The coincident γ rays were measured using four large volume germanium detectors mounted close to the implantation point and the neutrons were detected using 42 3He proportional counters. The measured γ-ray energy spectra are compared with shell model calculations and, where available, the level energies deduced from multinucleon transfer reactions.Received 1 February 1999DOI:https://doi.org/10.1103/PhysRevC.60.024311©1999 American Physical Society
