Resonance Radiation and Excited Atoms

Optical spectroscopy of radioactive atoms

“…The cause was eventually found in the resonance cells that were used. As when work on gas lasers first began, the above optical work also relied heavily on the book of Allan Mitchell and Mark Zemansky (the former at New York University) [62], in particular the resonance cells. The type of cell that was used at first was the "Wood's horn" (named after R.W.…”

Magnetic Enhancement of Ultraviolet Radiation Efficiency of Low-Pressure Hg-Ar Discharge

“…The quantum theory of the Zeeman effect (Ref. 12) shows that any level with angular momentum quantum number j splits into 2j + 1 sublevels in a magnetic field. Each sublevel has its own magnetic quantum number m which takes on values differing by unity from -j to +j.…”

Models for Infrared Atmospheric Radiation

“…The shape factor for the combined profile.is given by [21,22] . Several alternate and approximate forms of the Voigt function, and a number of tabulations of these forms, are available in [21,22,29,.…”

“…The shape factor for the combined profile.is given by [21,22] . Several alternate and approximate forms of the Voigt function, and a number of tabulations of these forms, are available in [21,22,29,. With the aid of computer programs developed by Hummer [41][42][43], Young [45,46], Armstrong [47], Chiarella and Reichel [48], and Gautschi [49,50], it is now possible to calculate the Voigt function (for an extended range of parameters) to an accuracy of better than six significant figures.…”
