为了寻找暗物质，我们描述了对样品辐射的第一次测量。这个样品由洛斯阿拉莫斯国家实验室核化学实验室拥有，由于它的高活度，用Ge探测器在1.2米的距离测量了它的通量。我们寻找不是由放射性衰变引起的，而是可能由于暗物质的非弹性散射而产生的核态。然后，在这个通量上得到的极限被转化为对非弹性暗物质参数空间的约束。最后，我们描述了未来研究的潜在范围。
We describe a first measurement of the radiation from asample to search for dark matter. Theflux from this sample, possessed by Los Alamos National Laboratory nuclear chemistry, was measured with a Ge detector at a distance of 1.2 m due to its high activity. We search for’s that cannot arise from the radioactive decay ofbut might arise from the production of a nuclear state due to the inelastic scattering with dark matter. The limits obtained on thisflux are then translated into constraints on the parameter space of inelastic dark matter. Finally, we describe the potential reach of future studies with.
