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

Abstract

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