In-beam {gamma}-ray spectroscopy in the ground-state proton emitter {sup 113}Cs

PDF Version Also Available for Download.

Description

Gamma-ray transitions in the ground-state proton emitter {sup 113}Cs have been identified using the reaction {sup 58}Ni({sup 58}Ni, p2n) at a beam energy of 230 MeV and the recoil decay tagging technique. The first experiment was done using the Recoil Mass Spectrometer at the Holifield Radioactive Ion Beam Facility where {gamma}-ray transitions were detected with 6 Clover and 5 Duet Ge detectors. A follow-up experiment using the GAMMASPHERE-FMA combination at Argonne National laboratory was performed. Ninety-six Ge and 4 LEPs detectors were used to record recoil-{gamma}{gamma} coincidences. Both experiments employed standard recoil mass separation techniques which resulted in the implantation ... continued below

Description

Gamma-ray transitions in the ground-state proton emitter {sup 113}Cs have been identified using the reaction {sup 58}Ni({sup 58}Ni, p2n) at a beam energy of 230 MeV and the recoil decay tagging technique. The first experiment was done using the Recoil Mass Spectrometer at the Holifield Radioactive Ion Beam Facility where {gamma}-ray transitions were detected with 6 Clover and 5 Duet Ge detectors. A follow-up experiment using the GAMMASPHERE-FMA combination at Argonne National laboratory was performed. Ninety-six Ge and 4 LEPs detectors were used to record recoil-{gamma}{gamma} coincidences. Both experiments employed standard recoil mass separation techniques which resulted in the implantation of A = 113 reaction products into a double-sided silicon-strip detector. By gating on the energy of the emitted proton and decay time, the correlation between {gamma} rays and the implanted {sup 113}Cs could be observed. Initial analysis and comparison with energy level systematics of the Cs isotopes reveal a decay sequence based on the h 11/2 bandhead. Further analysis is required to determine the decay of this sequence to the expected positive parity ground state.
