title: [Influence of the rate and the share of freezing water on hydrogen and oxygen separation].
abstract: The influence of the rate nu and the share of freezing water g on the separation of hydrogen D and oxygen 18O has been studied by mass spectromertry. Evidence was obtained supporting the well known facts that, upon freezing of water: (1) the concentration of D in ice is higher than in water; (2) the degree of separation for D is higher than for 18O; (3) an increase in the concentration of D and 18O in ice takes place as the nu value decreases. It was shown for the first time that, at g < 0.05, the concentrations of D at high nu values are higher than at g > 0.05, and at low nu values, it is less than at g > 0.05.
