The Structure of the He₂ 600 A Emission Continuum in the Region from 700 to 900 A

Abstract

The oscillatory structure of the He₂ 600 A emission continuum has been observed in He glow discharges using photon-counting technique, and new three peaks have been found in the wavelength region from 700 to 900 A. Comparison with calculations indicates that Sando’s potentials of A¹Σ_u⁺ and X¹Σ_g⁺ states reproduce the newly observed peaks very well. As for the ground state X¹Σ_g⁺ potential, its validity has been confirmed in the energy range from 3 to 7 eV.
