A STUDY OF HYDROGEN EXCITATION AND IONIZATION IN SOLAR PROMINENCES.
Abstract
The mechanisms of hydrogen excitation and ionization are discussed on the basis of known results. Expressions for 7 atomic processes which determine the propulation of hydrogen atoms are discussed. These expressions contain a number of unknown quantities which are determined by solving the system of stability equations. This allows for the calculation of the numbers of all the atomic processes. A comparison of their values leads to the conclusions: (1) the hydrogen excitation in prominences is determined mainly by their proper radiation, (2) for the high levels hydrogen ionization is caused by electron collisions, for low levels photoionization plays a more important role.
