Data in the λ2090 B region of HD 76932 have been obtained at high S/N using the HST GHRS echelle at a resolution of 90,000. This wavelength region has been previously identified as a likely candidate for observing the B/B isotopic splitting. The observations do not match a calculated line profile extremely well at any abundance for any isotopic ratio. If the B abundance previously determined fr...
متن کاملBoron in Diamond on Isotopic Mass
Kim et al. have reported a dependence of the infrared excitation energies of boron acceptors in diamond on the isotopic mass of the carbon atoms. We show that this change can be quantitatively interpreted as induced by a change in the hole effective mass.
متن کاملDetermination of isotopic ratio of boron in boric acid using laser mass spectrometry.
A reflectron time-of-flight mass spectrometer (RTOFMS) with a laser ablation ion source was used to determine the isotopic ratio of 10B/11B present in boric acid solutions, using graphite as the matrix. The atom % 10B values obtained were within +/-1% of the actual ones. The determination of the boron isotopic ratio using this method is, in comparison to other methods, faster, less expensive an...

Strong Limits on the Infrared Spectrum of HD 209458
We present a brief summary of observations of the transiting extrasolar planet, HD209458 b, designed to detect the secondary eclipse. We employ the method of ‘occultation spectroscopy’, which searches in combined light (star and planet) for the disappearance and reappearance of weak infrared spectral features due to the planet as it passes behind the star and reappears. We have searched for a c...
