A STUDY OF HYDROGEN LINES BROADENING IN AN IN TENSE IMPULSIVE DISCHARGE
Abstract
Spectra of an intense impulsive discharge in hydrogen were obtained by means of a spectrograph with a diffraction Echelle-grating. A spectrophotometric study of the broadening of hydrogen emission wings gives the following results: (a) When observing the spectra of a self-contracted discharge in a perpendicular direction the emission of hydrogen line wings (extending to 30-40A) is broadened due mainly to the linear Stark effect; (b) At P 0.5 mm Hg the emission extends to 50-80A and is broadened in the wing, probably due mainly to the quadratic Stark effect; (c) When the spectra are observed along the plasma discharge the broadening of hydrogen emission in the wings is due to macroscopic plasma motions with velocites about 10 to the 8th power cm/sec. The intensity variations in the wings are well explained by the supposition on directed plasma motion of the jet type along the axis of discharge with velocity gradients; (d) In observations outside the axis of discharge the broadening of hydrogen emission in the transversal as well as the longitudinal direction (near the discharge) is wholly due to the linear Stark effect.
