Photoionization of the alkali molecular ions in geo-cosmical plasmas

Abstract

Opacities of the solar and stellar atmospheres are caused by a large number of radiative processes. Within development of more sophisticated stel-lar atmosphere models, we can further investigate known processes and include all processes not considered before. We calculate the average cross-section and rate coe±cients for the photodissociation of the alkali molecular ions Li+2 , Na+2 and LiNa+ ready for further use with a particular accent to the applications for astro plasma research and low temperature laboratory plasma research.
