Scattering of thermal electrons at excited hydrogen atoms forms resonances, from which absorption features may arise, if the resonances donot decay by electron emission before; these absorption features agree in wavelengths with those observed in normal early type stars ( T eff ∼ 10 4 K) and predominantly in magnetic stars. It is shown that the conditions for the formation of the resonances, the quasistable states of H − , are just most convenient for the stars in question.
