Abstract

Vacuum ultraviolet atomic nitrogen and oxygen lines can contribute significantly to the transfer of energy in a high-density plasma for temperatures in the order of 1 eV. To calculate the amount of energy transferred via these lines for optically thick conditions, the $f$ value and Stark half-widths are needed. This paper presents experimental measurements of these parameters which were obtained from a graphical solution to the curve of growth. The results are compared with theory and other experimental data. A comparison is also made between experiment and theory for the radiation emitted normally from an infinite homogeneous slab by the strongest ultraviolet multiplets of these gases.
