Abstract

Previously unknown properties of neutron rich Ge-Br isotopes have been studied at the NSCL at Michigan State University. Production was by fragmentation of a 120 MeV/u ¹³⁶Xe beam on a Be target. The A1900 fragment separator blocked unwanted species produced in this reaction. The transmitted nuclei were implanted in a dual-sided silicon detector, which was part of the Beta Counting System detector. Implanted nuclei were identified by the ΔE-time of flight method. Beta decays were then identified as low gain signals from the same pixel as a previous implant. Beta-delayed neutrons were detected by the NERO neutron counter, which surrounded the Beta Counting System. This provided measurements of the β decay half-lives and β-delayed neutron emission probabilities.
