Inelastic X-ray scattering
= Inelastic X-ray scattering
<Inelastic X-ray scattering> measures <energy> and <momentum> transferred from <X-rays> to matter. With sufficiently high <energy resolution>, it can map a <phonon dispersion relation> by measuring inelastic peaks at different momentum transfers. <Crystal momentum> is determined modulo a <reciprocal lattice> vector.
