“…These neutrons typically thermalize in the shielding around the xenon before capturing. It is possible to reject a significant fraction of this background by identifying the production of 137 Xe and implementing a veto to remove the subsequent decays (3.8 minute half-life [8]) from the dataset.…”

136 Xe is a 0νββ decay candidate isotope, and is used in multiple experiments searching for this hypothetical decay mode. These experiments require precise information about neutron capture for their background characterization and minimization. Thermal and resonant neutron capture on 136 Xe have been measured at the Detector for Advanced Neutron Capture Experiments (DANCE) at the Los Alamos Neutron Science Center. A neutron beam ranging from thermal energy to greater than 100 keV was incident on a gas cell filled with isotopically pure 136 Xe. The relative neutron capture cross sections for neutrons at thermal energies and the first resonance at 2.154 keV have been measured, yielding a new absolute measurement of 0.238 ± 0.019 b for the thermal neutron capture cross section. Additionally, the γ cascades for captures at both energies have been measured, and cascade models have been developed which may be used by 0νββ experiments using 136 Xe.

“…Since then there has been surprisingly little progress in the investigation of neutron-rich Kr and Xe nuclei. A number of short-lived Kr and Xe isotopes were measured at various ISOL facilities [4][5][6][7][8][9][10][11], however, these studies were limited to 91−94 Kr and 139−143 Xe. The heaviest noble-gas isotopes known so far, 95 Kr and 144,145 Xe [12], were in fact obtained in earlier experiments utilising emanation, chemical separation and gas-jet techniques [13][14][15][16][17].…”
