• The profiles of H. and H/, were measured in a shock heated plasma of highelectron density of l to 3 X 10"cm '. The measured profiles are comparedwith the theoretical ones, and some discrepancies are pointed out ; the measuredhalf width is larger than the theoretical one for H., and the measured depth ofthe central dip of Hp is smaller than the depth calculated by theories. The depend-ence of the measured depth of the dip on electron density agrees with the extrapola-tion from the experimental result by Wiese et at. in electron density less than IQ"cm ', which indicates the effect of the ion motion. The measured value of thedegree of asymmetry of Hp profile, i.e., the ratio of the difference between theblue and the red peak intensity to the blue one, is approximately predicted by thetheory including the effect of the quadrupole interaction between a radiating atomand the nearest ion.
