The Lorentzian width of the spectral line Hel 504.7 nm emitted in the negative glow of a hollow cathode discharge (HCD) was found to increase depending on the distance from the emitting volume to the cathode axis. This effect manifests itself at low buffer gas pressures pHe E[epsolon](0.0-0.28) Torr. The later is typical for the experiments on SFS, radiative width and other constants. Thus, the observed radial inhomogeneity concerns the accuracy of these measurements. It is checked by determination of radiative width of the Hel 504.7 nm line emitted by two regions along the radius of HCD.
