Shift measurements of H α and H β lines in arc plasmas

Red shifts are reported for the H α and H β lines at electron densities of 10 16–10 17 cm -3. The peak shift of the H α line agrees with the ELC shift. For the H β line, the dip shift exceeds the ELC shift systematically. The H β dip shift is proportional to N e / T.
