Laboratory Experiment for Polarized Scattering at Potassium Vapor

摘要

The observed solar polarization peaks of the D 1 lines of sodium at 5896 A and barium at 4934 A still elude theoretical explanation, in spite of considerable theoretical efforts over the past decade. To clarify the underlying physics of D 1 scattering we have set up a laboratory experiment to explore the spectrally resolved profiles of the Mueller matrix for D_saD1catnte_rind2g at potassium vapor. Here we present initial results of this experiment.
