本文报道了对一硫化铀在M-4、M-5吸收边的磁康普顿散射（MCS）和X射线磁圆二色性（XMCD）的测量结果。从MCS实验中，我们得到了本地化（5 f电子）和扩散（主要是6d电子）的贡献的自旋矩。结合这些结果与体磁化和公布的中子衍射数据，我们可以分离的轨道和自旋的本地化和扩散的时刻的贡献。利用XMCD测量，我们推导出了磁偶极子算符的期望值。最后，我们比较我们的结果与发表的测量USe和UTe。
We report the results of two experiments performed on uranium monosulphide: measuring the magnetic Compton scattering (MCS) and x-ray magnetic circular dichroism (XMCD) at the M-4,M-5 uranium absorption edges. From the MCS experiment we get the spin moment of both the localized (5f electrons) and the diffuse (mainly 6d electrons) contributions. Combining these results with bulk magnetization and published neutron diffraction data, we can separate the orbital and spin contributions to the localized and diffuse moments. Using the XMCD measurements, we deduce the expectation value of the magnetic dipole operator. We finally compare our results on US with published measurements made on USe and UTe.
