 liquid para hydrogen at 20k computed with leapr.                 
 the scattering law is based on the model of keinert and sax,     
 which includes spin correlations from the young and koppel       
 model, diffusion and local hindered motions from an              
 effective translational scattering law based on a frequency      
 distribution, and intermolecular coherence after vinyard.
