Fe kalpha
Tīmeklis2015. gada 9. febr. · The Fe Kalpha emission line is the most ubiquitous feature in the X-ray spectra of active galactic nuclei (AGN), but the origin of its narrow core remains … TīmeklisThe Fe and Ag Kalpha line emission is at 6.4 keV and 22.2 keV respectively. The emission energy and spectra at these new photon energies has been characterized using three different detector systems which include a filtered PIN diode detector, pulse height spectrometer using a CdTe detector along with multichannel analyzer and a …

TīmeklisThe Fe Kalpha emission line feature in the 1993 ASCA spectra can be modeled with a complex of broad and narrow components at energies consistent with highly ionized Iron. However, the Fe Kalpha emission line in the 1995 spectra has only a single, narrow component and is consistent with emission due to neutral Iron. TīmeklisWhen that component is taken into account, the Fe Kalpha lines in the ASCA data are found to be unresolved in most cases, and to have equivalent widths <~200 eV, consistent with the Ginga data. Multiple observations of 3C 382 and 390.3 show the Fe Kalpha line approximately constant in flux but accompanied by strong continuum …

TīmeklisWe also detect emission lines and fit as Gaussians at 6.406^+0.004_-0.021 keV (Fe Kalpha) and 2.44^+0.04_-0.03 keV (S XV He_alpha). The continuum emission of Cen X-3 is consistent with two absorbed power laws, each of them modified by different absorbing columns and with the same power law index. http://hyperphysics.phy-astr.gsu.edu/hbase/Tables/kxray.html

TīmeklisSignificant Fe Kalpha peaks were generated during 100-sec counts when single ferritin molecules were excited with a probe current of 0.35 nA/60 nm spot, less than the maximal current available in a thermionic gun. There was a linear relationship between the number of ferritin molecules analyzed and count rates. cloud first cabinet officeTīmeklisThe Fe Kalpha line is particularly important because it is by far the strongest X-ray line observable in AGN spectra. Its profile carries the kinematic signature of the line-emitting gas and as such is constitutes an extremely useful diagnostic tool.
