论文摘要
在本文中，作为我们关于WIMP裂成靶核的后坐力通量和WIMP有效散射速度分布的研究的研究的补充，我们研究了WIMP入射速度的散射概率分布与窄后排能量中的核后退角度的核路后退速度的散射概率分布。我们的仿真结果表明，不仅入射晕杆的速度分布，而且后坐力角度的一个因子都会影响给定后坐力能量窗口中可用入射速度回复角组合的散射概率分布。因此，与所考虑的狭窄能量窗口相对应的1-D WIMP“有效”速度分布与仅从入射晕him的（生成）速度分布中切出的狭窄窗口不一致。因此，它对在考虑的能量窗口中对差异的wimp-核散射速率的贡献不能简单地通过在1-D理论速度分布（整个Halo Wimps的）中进行整合来估算。
In this paper, as a supplementary of our study on the angular distribution of the recoil flux of WIMP-scattered target nuclei and on that of the WIMP effective scattering velocity distribution, we investigate the scattering probability distribution of the WIMP incident velocity versus the nuclear recoil angle in narrow recoil energy windows for different WIMP masses and target nuclei. Our simulation results show that, not only the velocity distribution of incident halo WIMPs, but also a factor of the recoil angle could affect the scattering probability distribution of the available incident velocity-recoil angle combination in a given recoil energy window. Consequently, the 1-D WIMP "effective" velocity distribution corresponding to the considered narrow energy window would not be consistent with that cut simply from the (generating) velocity distribution of incident halo WIMPs. And its contribution to the differential WIMP-nucleus scattering event rate in the considered energy window could thus not be simply estimated by integrating over the 1-D theoretical velocity distribution (of entire halo WIMPs).
