Notes: From Davidson, 1973. Enrichment factors signify the amount that gas M will be enriched relative to gas M'. Theoretical enrichment factors were determined according to occupation of similar lattice vacancies, which may not be the case for different noble gases (from Davidson, 1973). ND = not determined.
