衍射和反射是不同的光学现象,它们是可以比较的;而X射线和可见光都分别能进行衍射或反射,所以对X射线...
由于对该射线性质一无所知,伦琴将其命名为X射线 (X-ray)。到20世纪30年代,人们以固态纤维和胶态粉末为研究物质发现了小角度X射线散射现象。 当X射线照射到 6、试样上时,如果试样内部存在纳米尺度的电子密度不均匀区,则会在入射光束周围的小角度范围内(一般2 6)出现散射X射线,这种现象称为X射线小角散射或小...
XPS X-Ray Sources In XPS instruments, X-rays are generated by bombarding a metallic anode with high-energy electrons. The energy of the emitted X-rays depends on the anode material, and the beam intensity depends on the electron current striking the anode and its energy. ...
