Detection of interstellar boron in front of kappa OrionusThe detection of interstellar boron in the direction of kappa Ori, obtained with the Copernicus satellite telescope by observing the B II 1362.46-A resonance line is reported. A B/H concentration ratio of (1.5 + or - 0.7) x 10 to the -10th (2 standard deviation error bar) is obtained. The main uncertainty lies in the determination of the continuum of the star in that wavelength region, dominated by a broad stellar absorption feature. The value inferred for B/H in the interstellar medium is consistent with the solar and stellar values, believed to be the galactic value, and with the theory of the production of B by cosmic rays in the interstellar medium.
