Abstract
The Doppler effect reduces the radiative interaction between identical atoms so that only those for which k. Delta v <or approximately= pi Gamma can couple coherently (where Delta v is the relative velocity, k=2 pi / lambda and Gamma is the lifetime of the isolated atom). The authors conclude that this coherent interaction cannot explain the 'extrapolation anomaly' of resonance broadening.Keywords
