متن کاملElemental Composition from Gamma-ray Spectroscopy of the Near-shoemaker Landing Site on 433 Eros
Elemental composition and composition ratios derived from gamma-ray measurements collected by the NEAR-Shoemaker spacecraft while on the surface of 433 Eros are reported. Performance of the gamma-ray spectrometer (GRS) during cruise and orbit is reviewed. The best gamma-ray data were collected on the surface of Eros after the spacecraft’s controlled descent on 12 February 2001. Methods used in ...
متن کاملElemental composition of 433 Eros: New calibration of the NEAR-Shoemaker XRS data
Introduction: We present relative elemental abundances for six elements (Mg, Al, Si, S, Ca, Fe) in the surface layer of 433 Eros, derived from a new analysis of the solar-induced fluorescence measured by the NEAR-Shoemaker X-ray Spectrometer (XRS). XRS-derived elemental abundances have been presented before [1,2]. However, calibration of XRS data depends critically on knowledge of the incident ...

tected, as it were, from another crossing over. This relation is illustrated in the diagram (fig. 7). If crossing over occurs at some point between two pairs of factors a and b indicated on the diagram, the next crossing over point of the chromosome would, if it occurred at all, lie at some distance away, rather than near by. This possibility can be tested in a case where several known points a...
