DESCRIPTION:Speakers: Chami Amarasinghe (University of Michigan)\nWe propo
 se a technique for an ultra-low energy nuclear-recoil measurement in liqui
 d xenon using thermal neutron capture. The measurement uses the recoils im
 parted to xenon nuclei during the de-excitation process following neutron 
 capture\, where the promptly emitted $\\gamma$ cascade can leave the nucle
 i with up to $0.3$ keV$_\\text{nr}$ of recoil energy. A successful measure
 ment of the quanta yields below this point will contribute to a greater se
 nsitivity for liquid xenon experiments that will benefit from a lower ener
 gy threshold\, mainly those searching for light WIMPs and coherent neutrin
 o-nucleus scattering. We describe the proposed measurement and its feasibi
 lity for a small (sub-kilogram) LXe detector that is optimized for a high 
 scintillation gain\, and a pulsed neutron source.\n\nhttps://indico.physic
