Production of an Intense Helium Continuum below 230 Å

Abstract

Using a capillary spark in helium, we have produced the He ii line spectrum between 303.8 and 230.7 Å, as well as an intense helium continuum between 228.8 Å and approximately 120 Å. Three autoionized resonance transitions of helium between 206.2 and 192.2 Å were studied by use of the helium continuum.
