ON THE QUESTION OF ISOTOPIC PHASE SEPARATION IN SOLID H2 - D2 MIXTURES,
Abstract
The purpose of the research was to investigate possible isotopic phase separation in solid H2 - D2 mixtures by observing line widths and line shapes of nuclear resonance. A calculation of the rigid lattice second moment for protons in a homogeneous solid H2 - D2 mixture was made. Observations of the N.M.R. line widths and line shapes of solid mixtures of n-H2 and n-D2 at 4.2 K showed the line shapes to be Gaussian and yielded widths which are illustrated. The calculated shape of the derivative of a resonance line obtained from a phase separation of a sample of original concentration X sub H2 = 0.20 into regions with concentration X sub H2 = 0.95 and X sub H2 = 0.05 is presented. The composite nature of the line is evident. (Author)
