钒的[100]、[110]和[111]康普顿谱以0.12原子单位的动量分辨率测量。观察到的剖面具有精细的结构和方向各向异性。与APW波段理论预测结果的比较表明，波段理论高估了低动量时的动量密度，而低估了高动量时的动量密度。该理论还过分强调了各向异性的精细结构和尺度。
The [100], [110] and [111] Compton profiles of vanadium are measured with a momentum resolution of 0.12 atomic units. The observed profiles have fine structures and directional anisotropies. Comparison of the results with the APW band theoretical predictions shows that the band theory overestimates the momentum density at low momenta and underestimates it at high momenta. The theory also overemphasizes the fine structures and the scale of the anisotropies.
