Photoionization and photodissociation rates in solar and blackbody radiation fields

Rate coefficients for ionization and dissociation have been calculated for over 140 atomic, molecular, and ionic species in the radiation fields of (1) the quiet and the active Sun at 1 AU heliocentric distance and (2) blackbodies at four selected temperatures in the range from T=1000 K to 1,000,000 K without factors for radiation dilution with distance from the source. The rate coefficients in units of transitions per second ( s − 1 ) and associated excess energies of the photo products in eV are tabulated for about 265 ionization, dissociation, and dissociative ionization branches.
