Spectral Line - an overview ScienceDirect Topics

WebA single spectral line at a certain spectral position is fully characterized by its strength (the intensity, or integrated absorption coefficient) and its line half-width (plus knowledge of the broadening mechanism, i.e., collision and/or Doppler broadening). WebApr 29, 2014 · Signal processing Electron density Transition metals ABSTRACT Two Stark broadening parameters including FWHM (full width at half maximum) and FWHA (full width at half area) of isotope hydrogen alpha lines are simultaneously introduced to determine the electron density of a pulsed vacuum arc jet. WebThe broadening of spectral lines in dense plasmas primarily stems from a com-plex interaction of an emitting atom with the perturbing plasma constituents [1]. Accordingly, the line shapes and shifts reveal (generally non-trivial) de-pendence on major plasma characteristics such as particle density and tem- cleveland state university enrollment fee
