Abstract

The plasma-broadened

H_{α}

and

H_{β}

spectral-line profiles of hydrogen were calculated retaining the time ordering in the

S

matrices of the width-shift operator by diagonalizing with the O(4) group. Significant changes occur: The

H_{α}

peak is decreased 15%, the half-width is increased 25%, and the

H_{β}

relative dip is decreased 23% without significant alteration of the maximum intensity of half-width. Agreement with experiment is improved appreciably.
