Stark broadening parameters (widths and shifts) of two He I isolated spectral lines are measured in a plasma of a low-pressure pulsed arc. Plasma electron densities, determined by spectroscopic method based on previously calibrated He I lines, ranges from 1 x 1016 cm-3 to 6 x 1016 cm-3. The plasma electron temperature acquired by a Boltzmann plot of several He I lines, lies in the interval 8 000-30 000 K. Results of this work are compared with theoretical predictions and with other experimental data.
