Between 1 MHz and 55 GHz the complex dielectric spectrum has been measured at 25ยฐC for D,O and for HsO/DsO mixtures with mole fraction x=0.25, 0.5 and 0.75 of DzO. A Debye-type relaxation spectral function has been fitted to the frequencydependent data to yield the static permittivity, the extrapola

The results are especially encouraging in the light of Konowalov's calculation [8]. He found that Hulth&n functions (integral transforms of 1s functions), which are somewhat better than k,(q) in the Z-electron+atomic case, reduce to scaled 1s functions in H2, except for larger R values. Since k, (v)
