Collisionbroadened spectral line profiles in the limit of high perturber density
Abstract
In the present research we have used a Fourier spectral analysis to study line profiles due to strong atomatom interactions in the limit of high perturber density. The presence of multiple satellites in this case is well explained. Moreover, for decreasing interactions and densities we may extrapolate our results and explain the disappearance of the satellites. The use of ``a crude potential shape''here a squarewellproves to be sufficient to explain the presence of multiple satellites and determine the necessary physical conditions for their appearance.
