Profile measurements of the lines HeI 4471 and 4922 in a dense plasma Nelson, Robert Howard
Detailed measurements were made of the profiles of the lines HeI 4471 and 4922 Å in a pulsed arc plasma, for electron densities in the range 3 x l0(16) to l0(17) cm(-3) and at a temperature of 4.5 eV. Photoelectric detection was employed in a rapid scan spectrometer. The relative intensities agreed well with the computed values, but the component peaks for each line were closer together.
