Laboratory frequency redistribution function for the polarized λ-type three-term atom

Listed in National Center for Atmospheric Research

We present the frequency redistribution function for a polarized three-term atom of the Lambda-type in the collisionless regime, and we specialize it to the case where both the initial and final terms of the three-state transition are metastable (i. e., with infinitely sharp levels).

Description

This redistribution function represents a generalization of the wellknown RII function to the case where the lower terms of the transition can be polarized and carry atomic coherence, and it can be applied to the investigation of polarized line formation in tenuous plasmas, where collisional rates may be low enough that anisotropy-induced atomic polarization survives even in the case of metastable levels.
