Atomic Line Transitions and Radiation From High Temperature Air

Abstract

The status of the current investigation into the radiant emission from high temperature air is described. A treatment of emission by molecular species and some new results in line broadening is included. Results are presented "or air at temperatures 0.5 to 5.0 eV and densities from 1.0 to 10 4 times normal. i-'° I.

“…Bethe. From the 1950s through the 1970s, research on opacities was supported by AFSWC, A m , Los Alamos Scientific Laboratory, the Air Force Office of Scientific Research, Naval Research Laboratory, Defense Atomic Support Agency, and DNA. Experimental and theoretical work was carried out at RAND Corporation (Gilrnore and Latter 1956;Gilmore 1958), Lockheed (Churchill, Hagstrom, and Landshoff 1964;Churchill et al 1966;Buttrey and McChesney 1965;Mueller 1963;Johnston and Platas 1969;Armstrong et al 1958;Churchill et al 1962;Johnston et al 1971), AVCO Corporation (Allen et al 1962;Keck et al 1963;Taylor 1960;Taylor and Caledonia 1968;Wray and Taylor 1969;Keck et al 1959;%vel and Bailey 1957;Camrn et al 1967;Wentink et al 1967;), Los Alamos Scientific Laboratory (Mayer 1947;Cox and Stewart 1964), AFWL (Harris and Sullo 1970;Generosa and Harris 1970;and Harris et al 1969), General Electric Corporation (Breene 1966), California Institute of Technology (Patch et al 1962), and elsewhere. Funding for opacity work tapered off sharply in the 1970s.…”
