Meteorites : Classification and Properties

Autor: J. T. Wasson

My goal in writing this book was to provide an introduction to meteorite science and a handbook on meteorite classification. Insofar as I succeeded it should prove useful both to the practicing professional and to university students at the upper-div

Bitburg—a group-IB iron meteorite with silicate inclusions

Autor: E. Jagoutz, And J. T. Wasson, E. Rambaldi

Publikováno v: Mineralogical Magazine. 39:595-600

SUMMARY. Chemical and mineralogical investigations show that the Bitburg meteorite is not a pallasite, but a group-IB iron meteorite. Like other members of this group it contains chondritic silicates. THE Bitburg meteorite is the largest meteorite di

The period covered by this report, 1984 July to 1987 June, was of extraordinary importance for the progress of cometary physics. For the first time in the history, special space probes were launched to comets. Vega 1, Vega 2 and Giotto encountered P/

M. M. Woolfson. Under the conditions of the capture theory, planets were originally formed in highly eccentric orbits which were close to, but not exactly coplanar. A resisting medium rounded off these orbits but, because it produced a non-central gr

Be7, P32, P33, and S35: Stratospheric concentrations and artificial production

Autor: N. A. Dimond, P. J. Drevinsky, E. C. Couble, J. T. Wasson

Publikováno v: Journal of Geophysical Research. 69:1457-1467

Cosmic-ray-produced Be7, P32, P33, and S35 radioactivities have been measured in aircraft filter collections made at 20 km over the central United States during 1961 and 1962. Fission products Ba140 and Sr90 have been measured in the same samples. Ob

Decay ofI134

Autor: G. D. O'Kelley, Noah R. Johnson, J. T. Wasson, J. W. Chase, E. Eichler

Publikováno v: Physical Review. 122:1546-1558

The decay properties of 53 min I/sup 1//sup 3//sup 4/ were investigated with scintillation techniques. Energies (and intensities) of the gamma rays determined from the single-cryatal and coincidence studies were 0.135 (3.2), 0.18, 0.23, 0.27, 0.32, e

On the origin of the sodium present in the upper atmosphere

Autor: C. E. Junge, J. T. Wasson, O. Oldenberg

Publikováno v: Journal of Geophysical Research. 67:1027-1039

Various origins are considered for the atmospheric sodium observed in the twilight and nightglow above an altitude of 70 km. The transport of sea salt to these altitudes in sufficient quantities seems impossible except in the unlikely case of complet
