Identifying excited states in 35S via 34S(d,pγ)

An experiment was conducted at FSU’s John D. Fox Accelerator Laboratory to improve the systematics of the sparsely researched ³⁵S. The goal is to contribute to understanding the systematics of the l = 1 and l = 3 splittings for N = 19 isotones, and help explain the sudden changes to the nuclei such as ³⁴Si claimed to have a proton bubble. A 16 MeV deuteron beam was directed toward a ³⁴S target using a tandem accelerator. This neutron transfer reaction was performed using the Super-Enge Split-Pole Spectrograph with an interior focal plane detector located at 37 degrees. Seven CeBr₃ PMT detectors surrounded the reaction target. Using the positions of the protons observed by the focal plane detector, we determined energies of excited states. ³⁵S states (1.99, 2.34, 4.903, and 4.963 keV) were identified and confirmed by gamma ray coincidences. Furthermore, we determined the lifetime of the 1.99 MeV state in ³⁵S using the time-difference between CeBr₃ gamma ray detectors and protons detected in the Super-Enge Split-Pole Spectrograph. Preliminary results will be presented.
