  • Refractive index of carbon tetrafluoride (CF4) in the 300-140

    Jul 15, 1990 · Conclusion From the liquid-CF4 measurement the Abbe number for 144, 150 and 155.6 nm was expected to be around 85, versus 53 for helium. The present results show that it should be rather taken as 31. It should therefore be considered that helium is still the best gas to be used as a radiator in Cherenkov detectors and that in many cases achromatisation devices cannot be avoided.
