I. Seipp et W. Schweizer, ELECTRIC-FIELDS FOR HYDROGEN BOUND-FREE TRANSITIONS IN MAGNETIC WHITE-DWARFS, Astronomy and astrophysics, 318(3), 1997, pp. 990-996
We present photoionization spectra at optical wavelengths for hydrogen
in strong parallel electric and magnetic fields for magnetic white dw
arfs obtained with the complex coordinate method. It is shown that spe
ctra calculated for fixed magnetic and electric fields can be averaged
over a distribution of electric fields. Such averaged spectra are pre
sented for fixed magnetic field with a Holtsmark distribution of elect
ric fields at wavelengths around 580 nm interesting for a stationary l
ine at 23 500 T.
