| Abstract: | The observed solar polarization peaks of the D$_1$ lines of sodium at 5896~{\AA} and barium at 4934~{\AA} 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$_1$ and D$_2$ scattering on potassium vapor as a function of the magnetic field. Here we present the results of this experiment. |
