讨论了非零动量转移时超对称暗物质粒子与原子核的散射问题。在简要处理了自旋无关的形式因子之后，我们仔细地阐述了自旋相关的散射问题。最后，我们计算了131Xe的自旋相关截面；它随着动量转移的增加而减小，但比自旋无关的截面要慢得多。
We discuss the scattering of supersymmetric dark matter particles from nuclei at nonzero momentum transfer. After a brief treatment of spin-independent form factors, we carefully formulate the spin-dependent scattering problem. We conclude with a calculation of a spin-dependent cross section in131Xe; it falls as the momentum transfer increases, but more slowly than the spin-independent cross section.
