Coherent elastic neutrino-nucleus scattering and low-mass dark matter detectors rely crucially on the understanding of their response to nuclear recoils. We report the first observation of a nuclear recoil peak at around 112 eV induced by neutron capture. The measurement was performed with a cryogenic detector from the NUCLEUS experiment exposed to a source placed in a compact moderator. We identify the expected peak structure from the single- de-excitation of with and its origin by neutron capture with significance. This result demonstrates a new method for precise, in situ, and nonintrusive calibration of low-threshold experiments.

中子俘获引起的 100 eV 级核反冲峰的观察
相干弹性中微子核散射和低质量暗物质探测器关键依赖于了解它们对核反冲的反应。我们报告了第一次观察到由中子俘获引起的大约 112 eV 的核反冲峰。测量是用一个来自 NUCLEUS 实验的低温探测器暴露在源放在紧凑的版主中。我们从 single- 中识别出预期的峰结构去励磁和及其中子俘获的起源意义。这一结果展示了一种用于低阈值实验的精确、原位和非侵入式校准的新方法。
