Abstract : The authors have observed weak satellites to the lines of the principal series of the helium and hydrogen like ions of magnesium, aluminum, silicon and sulphur in the solar spectrum. These lines coincide in wavelength with the extrapolated positions of transitions from the autoionizing levels in helium like ions, and the autoionizing levels in lithium like ions. The observations provide direct evidence of dielectric recombination in the corona. (Author)
