Abstract
The profile and the shift of the H(alpha) line of hydrogen were measur ed and the shift was calculated at high electron densities in a helium plasma. The plasma was produced in a gas-liner pinch, which was diagn osed by Thomson scattering. Densities were between 1 X 10(18) cm-3 and 1 X 10(19) cm-3 and temperatures varied from 4 up to 12.5 eV. The res ults show a nonlinear behavior of the shift. Corresponding theoretical calculations have been performed, especially taking into account the dynamic screening of the electron-atom interaction. The agreement is v ery good for densities below 5 X 10(18) cm-3; above that density it is satisfactory.
