我们使用测量的核磁矩与一些非常一般的假设，核波函数，以估计自旋相关的弹性截面的超对称暗物质粒子的各种核。我们的截面几乎总是小于相应的单粒子估计。在有镜像伙伴的轻核中，我们除了利用磁矩外，还利用β衰变ft值，得到了更精确的结果。
We use measured nuclear magnetic moments together with some very general assumptions about nuclear wave functions to estimate the spin-dependent elastic cross sections of supersymmetric dark-matter particles on a variety of nuclei. Our cross sections are nearly always smaller than the corresponding single-particle estimates. In light nuclei with mirror partners, we make use of β-decay ft values in addition to magnetic moments and obtain even more accurate results.
