This paper shows the results of calculations, obtained by
computer simulation, of the Stark broadening of the
dipolar Lyman line of hydrogen considering
fine structure, of two–photon absorption profiles for
the transition 1S
2S of hydrogen and of the profiles
that could be obtained using two–photon polarization
spectroscopy techniques for the aforementioned
transition. Calculations have been carried forward
for wide ranges of electron density, between
4
1019 and 1023 m-3 and temperature,
between 2 000 and 100 000 K. We have considered
ion dynamics effects with perturbers of different masses.
In this paper we give the obtained profiles and the
autocorrelation functions. These autocorrelation
functions could be used in order to add another broadening
mechanisms before obtaining the spectral profiles.
