Scientific paper

The effect of chromospheric bombardment by an electron beam during solar flares is examined. Using a semiempirical flare model, energy balance at temperature minimum level and in the upper photosphere is investigated. It is shown that nonthermal hydrogen ionization leads to an increase of chromospheric hydrogen continuum emission, H(-) population, and absorption of photospheric and chromospheric continuum radiation. So the upper photosphere is radiatively heated by chromospheric continuum radiation produced by the beam. The effect of hydrogen ionization is an enhanced white-light emission both at chromospheric and photospheric level, due to Paschen and H(-) continua emission, respectively. White-light contrasts compatible with observations, obviously showing the link between white-light flares and atmospheric bombardment by electron beams are obtained.
