Can I read The calculation of the resonance escape factor of helium for Lorentzian and Voigt profiles on EtoBox?
The calculation of the resonance escape factor of helium for Lorentzian and Voigt profiles by Jian He; Qingguo Zhang is a Physics and Astronomy article available to read on EtoBox.
What is The calculation of the resonance escape factor of helium for Lorentzian and Voigt profiles about?
The resonance escape factors of helium 10830.34 Å, 10830.25 Å and 10829.08 Å that making up the 10830 Å emission lines are calculated, for both Lorentzian profile and Voigt profile. The total number of absorbing atoms in the ground state is calculated. The dependence of the escape factors on the optical depth in the line center is considered. The resonance escape factors of helium 3889 and 3118 emission lines are discussed also. This calculation is useful in the research on the helium in the sun and remote stars from the helium emission lines.
Who reads The calculation of the resonance escape factor of helium for Lorentzian and Voigt profiles?
It is typically read by researchers, students, and practitioners in Physics and Astronomy.
