摘要：

The main aim of this work is to estimate the total contribution to the opacity of DB white dwarf atmosphere of the processes of the He-2(+) molecular ion photo-dissociation and He + He+ collisional absorption charge exchange, and compare it with the contribution of He-, and other relevant, radiative absorption processes included in standard models.
