Abstract:
Inelastic processes in low-energy Ca+H and Ca++H- collisions
are treated for the states from the ground state up to the ionic
state, in order to provide rate coefficients needed for non-LTE
modeling of Ca in cool stellar atmospheres.
Electronic molecular structure was determined using a recently
proposed model approach based on an asymptotic method. Nonadiabatic
nuclear dynamics are treated by means of multichannel formulas, based
on the Landau-Zener model for nonadiabatic transition probabilities.
Description:
Rate coefficients in cm3/s for inelastic Ca+H and Ca++H-
collisions for temperatures from T=1000K to T=10000K.
