Abstract
In present work we examine a sample of Seyfert 2 galaxies in the near-IR, 0.8-2.4 μm, looking for HI and HeI recombination lines in order to study the physical properties of the region emitting HeI lines. For the HeIλ10830 it is important to consider collisional effects as a correction to the recombination cascade. For these purposes we apply the Benjamin et al. (1999, ApJ, 514, 307) model and take into account radiative transfer effects (Benjamin et al. 2002, ApJ, 569, 288).
