Beta-Delayed Neutron Branching Ratios of 33Mg

This work is focused on finding the beta-delayed neutron branching ratios following the beta decay of 33Mg. All the data studied here came from an experiment run in the TRIUMF lab in Vancouver-Canada in the fall of 2022. A laser ionized 33Mg ion beam was used and sent to the GRIFFIN spectrometer, SCEPTAR, and a new OGS neutron detector to measure the gamma ray, beta-decay electrons, and neutron coincidences that emerged from the decay of 33Mg, respectively.

The raw data was analyzed using GRSISort, a ROOT derivative analysis software, to produce different histograms, which were then used to eliminate background and other unfunctional data. Gamma-gamma coincident histograms that were gated on the beta particles and neutrons were used to develop the decay schemes of the beta-delayed neutron daughters. We checked our data against the data that had been produced before to make sure our results lined up with previous experiments. The analysis done on beta-delayed neutron branching ratios of 33Mg, 32Al, and the surrounding isotopes using the new OGS detector will be presented.
