Stark width of the 463.054 nm singly ionized nitrogen spectral line,
that belong to transition, have been measured in a linear pulsed,
low pressure, arc discharge. The working gas was helium-nitrogen-oxygen
mixture. Electron densities of 0.75 1023
to
1.45 1023
were determined in the electron temperature range between 30 000 K -
38 000 K. The measured values have been compared with our calculated
data, using the modified semiempirical approximation. On the basis of
the agreement among experimental and theoretical Stark width data, the
isolated 463.054 nm N II spectral line can be recommended as convenient
spectral line for plasma diagnostics.
