在样品居里温度附近的几个温度下，对已使用的单晶进行了磁康普顿散射实验。结合磁康普顿散射实验和磁化强度测量，推导出自旋和轨道使用力矩。此外，使用的自旋矩被分解为5f电子分量和扩散分量。得到了5f电子的自旋矩、5f电子的轨道矩和扩散矩。通过与以往UTE结果的比较，得出结论：从使用到UTE总磁化强度的增加主要归因于5f电子的自旋矩减小，而5f电子的轨道矩略有增加。从硫化物的U5f和U6d电子和/或U5f电子和价电子杂化的角度对结果进行了讨论。
Magnetic Compton scattering experiments on a USe single crystal have been performed at several temperatures around the Curie temperature of the specimen. The spin and the orbital moments of USe are deduced by combining the magnetic Compton scattering experiment with the magnetization measurement. Furthermore, the spin moment of USe is decomposed into a 5f electron component and a diffused component. We have obtained the spin moment of the 5f electron , the orbital moment of the 5f electron and the diffused moment . From comparison with the previous results of UTe, it is concluded that the increase of the total magnetization from USe to UTe can mainly be ascribed to the decrease in magnitude of spin moment of the 5f electron with a slight increase of the orbital moment of the 5f electron. The results are also discussed from the points of view on the hybridization between U 5f and U 6d electrons and/or U 5f electrons and valence electrons of chalcogenide.
