The Vibration-Rotation Emission Spectrum of Free BeH 2

) of the HDAand LDA structures are plotted in Fig. 1, B(neutron data) and D (x-ray data); also plottedare the data from the sample annealed at 105K. The annealed structures factors cannot beproduced by any combination of LDA andHDA. We note the region in Fig. 1D wherethe x-ray curves intersect at 2.05 A
