The Stark line profiles for hydrogen Ly α, Ly β , H α , and H β are calculated using the computer simulation method for helium plasmas in the range of electron concentration from 10 18 to 10 19 cm −3 at increasing temperature values kT from 7 to 10 eV , according to the experimental measurements in dense plasmas (Bochum experiment). The calculation was carried out at two limiting assumptions about the perturbers: (a) in the helium plasma only singly ionized helium ions occur, and (b) in the plasma the doubly ionized ions exclusively exist. In the paper the ratio of the calculated full half-widths, FWHM( b)/ FWHM( a), for these lines are presented. The ratio equals about to 1.1 for Ly β and H β lines, about 1.0 for H α , and about 0.9 for Ly α line.
