摘要：

We have found the refractive index of liquid orthodeuterium at 24.2 K and 3200 Å to be 1.1321 ± 0.0025. This is in agreement with the value calculated from the Lorentz-Lorenz relation, the Lorentz theory of the dielectric constant, and the measured dispersion of deuterium gas. Our measurements also yield a rough value for the difference in molecular polarizabilities of deuterium and hydrogen, Δαα = (2.3 ± 1.9)%. The measurement was a coincidental result of a particle-physics experiment in which Čerenkov counters were used with either liquid hydrogen or liquid deuterium as a radiating medium. The ratio of the refractive indices of the two substances was determined from the change in response of the counters when the radiating medium was changed. © 1969.
