The contribution of ion-atom radiative collisions to the opacity of the solar atmosphere
Abstract
We investigate the contribution to the opacity of the solar atmosphere of some processes other than formation and photodissociation of the H- ion. We show that positive-ion-atom radiative collision processes are not negligible at certain layers of the photosphere and of the chromosphere, although they make only a negligible contribution to the solar continuous optical emission emergent intensity.
