Absolute viscosity of D₂¹⁸O between 15 and 35°

Absolute viscosity values for highly enriched U₂¹⁸O samples have been measured at 5° intervals between 15 and 35° using a semiautomatic closed viscometer of the suspended-level type. The absolute viscosity of 100% D₂¹⁸O has been determined by extrapolation of the experimental data by means of Eyring's absolute rate theory of viscosity. In order to perform the above extrapolations certain assumptions had to be made concerning the nonnegligible amount of HDO present in the samples.
