Abstract
We report measured Stark widths of the HeII 121.5 nm line. A pulsed low pressure arc was used as a light source. The plasma conditions corresponded to electron temperature of 4.5 eV and electron densities in the range (3.9-6.2) x 1022 m-3. Electron densities derived from the comparison of the measured widths of 121.5 nm line and Kepple's theoretical results agree within ±5% with those obtained from the width of HeII Pashen-alpha (468.6 nm) line.
