在铁磁Ni单晶的220 Bragg反射中，首次观察到K吸收边的共振型x射线磁散射。进一步对观测到的共振磁散射曲线进行了理论讨论；从这条曲线还得到了自旋各方向振子强度密度的差异。在费米能级和以上25ev之间，少数自旋的振子强度密度超过多数自旋的振子强度密度。振子强度密度差最大时约为1×10 -4 /Ry。
A resonance-type X-ray magnetic scattering at the K -absorption edge was first observed in 220 Bragg reflection of ferromagnetic Ni single crystal. Further a theoretical discussion on the resonance magnetic scattering curve observed was carried out; A difference of the oscillator-strength density for each direction of the spins was also derived from this curve. The oscillator-strength density for minority spin excesses that for the majority spin between the Fermi level and 25 eV above the level. The difference of oscillator-strength density amounts to about 1×10 -4 /Ry at the maximum.
