High density self-broadening of the first xenon and krypton resonance line
2014 Self-broadening of the 146.96 nm xenon line and 123.58 nm krypton line is studied in the density range 1-100 amagat (2.7 x 1019 2014 2.7 1021 at. cm-3). The absorption profile is deduced from reflection experiments by a modified Kramers-Krönig analysis. A detailed discussion of the criteria for validity of available theories is given, allowing the determination of the extent to which the c...
متن کاملEffects of gases on photoionization of caesium by line absorption
Relative measurements of the photoionization by line absorption in caesium vapor with and without foreign gases were made by the space-charge method. If the effect of a collision with a gas molecule is to change the probability of ionization from E to Ef, then the probability E v at a gas pressure p is given by E -Ev E -EfV^ Aa*T'pJ where A is a known constant, a is the distance between atom ce...
متن کاملResonant Photoionization Mass Spectrometer for Determination of Isotopic Compositions of Krypton in Extraterrestrial Samples
Introduction: The isotope ratios of Krypton trapped in presolar SiC grains record the physical properties of s-process sites [1], while Kr isotopic measurements of small samples of primitive meteorites allow the irradiation environment of the early solar system to be investigated [2,3]. Extracting the maximum amount of information from such samples, especially those available in limited amounts...
متن کاملPolarized line formation by resonance scattering
The model two-level problem of non-LTE line formation in homogeneous plane atmospheres is reconsideredwith the complete account of polarization arising in resonance scattering. We use the approximation of complete frequency redistribution (CFR) and restrict our discussion to themost important case of axially symmetric radiation fields in semi-infinite atmospheres. The primary sources are assume...

Weconsidermultiple resonance scatteringwith complete frequency redistribution (CFR) in a semi-infinite conservative atmosphere (photon destruction probability εI = 0) with the sources at infinite depth. The polarization arising in resonance scattering is completely accounted for. The problemweconsider is the resonance-scattering counterpart of the ChandrasekharSobolev problem of Rayleigh scatte...
