## Absolute Intensity of Atom Line Formula

Absolute Intensity of Atom Line = (Gaseous Layer Thickness/(4*pi))*Transition Probability*Neutral Atoms Density*[hP]*Spectral Line Frequency
Iabs = (d/(4*pi))*Aqp*n*[hP]*νqp

The primary concept is that of the radiant flux of a source, that is, the amount of radiant energy emitted into space in unit time. Usually, we consider only a fraction of the total flux, namely the flux within a relatively small solid angle in the direction of observation, for example, the flux that reaches the dispersing medium or the detecting system.
