We present quasi-elastic neutron scattering measurements of liquid normal hydrogen under saturated vapor pressure. Empirical estimates of the self-diffusion constant are generally in good agreement with previous nuclear magnetic resonance studies. We consider available theoretical calculations of the transport properties of liquid hydrogen as well as the applicability of the Stokes–Einstein relation to this quantum liquid.

液氢的自扩散：准弹性中子散射研究

我们提出了饱和蒸气压下液态正态氢的准弹性中子散射测量。自扩散常数的经验估计通常与以前的核磁共振研究非常一致。我们考虑了液氢传输特性的可用理论计算以及斯托克斯-爱因斯坦关系对这种量子液体的适用性。
