重新研究了液态水的非弹性x射线散射光谱。在低动量转移情况下，偶极子近似是合理的，从IXS数据计算的反射光谱与光学光谱相当吻合。在有限动量传递时，数据以贝特曲面的形式呈现，其中传递的能量为0 ~ 200eV，传递的动量为0.19 ~ 3.59a.u.。观测到的特征比理论预测的模型更分散。
Inelastic X-ray scattering (IXS) spectra of liquid water are re-examined. At low momentum transfer the dipole approximation is justified and the reflectance spectrum calculated from IXS data agrees fairly well with the optical one. At finite momentum transfer the data are presented in the form of the Bethe surface where the energy transferred is from 0 to 200eV and the momentum transferred is from 0.19 to 3.59a.u. Observed features are more diffuse than those of the theoretically anticipated models.
