Popis:	Simultaneously recorded spatially-resolved profiles of He I 492.2 nm singlet line are used in hollow cathode discharge plasma diagnostic. A shift of the line center is observed. Both shift and lower pressure branch of Lorentz half-width depend equally on gas pressure and localization of the emitting plasma bulk along the radius. The observed effects are referred to the macroscopic electric field penetrating into negative glow. In this field the fast electrons of the electron energy distribution function keep their beam-like character in negative glow too.
