Pagination or Media Count:
Using the third-order spectrum of a 3-m grazing incidence-type vacuum spectrograph, the 600-A band of helium was studied in combination with an uncondensed discharge of helium operated at liquid-nitrogen temperature as well as at room temperature. The observed intensity enhancement of the neon line at 600.04 A is also discussed with relation to the 600-A band. Author
