Abstract

Inspection of the previously published data on boron reveals less than a dozen spectral lines attributed to this element in the region of longer wave length than 1850 Angstrom units.1, 2 A consideration of the series spectra of the various stages of ionization of boron however shows that a considerably larger number of lines is to be expected in this region. The present work was undertaken to see whether with the vacuum spark as a source and spectrographs of medium dispersion some of these lines could be found.
