abstract = {Stark broadening of hydrogen lines in the presence of a
magnetic field is revisited, with emphasis on the role of
the ion component under typical conditions of magnetized
fusion devices. An impact theory for ions valid at low
density (N-e less than or similar to 10(14) cm(-3)) and
taking into account the Zeeman degeneracy removal of the
atomic states is developed. It is shown that the Stark
widths of the Lorentz triplet components strongly depend on
the magnetic field. The model is validated by a computer
simulation method. For the lateral sigma components of Ly
alpha, we show that the impact approximation still holds for
densities as high as N-e similar to 10(15) cm(-3). In
contrast, for the central pi component as well as for the
other lines from low principal quantum number, significant
discrepancies between the proposed theory and the simulation
results appear at high density. Application to D alpha in
tokamak divertor plasma conditions shows that, in this case,
the quasistatic approximation becomes more relevant.},
