Zeeman spectra of the green e-a transition of FeH and of two Fe(I) lines

Files contain Zeeman-resolved patterns of two Fe(I) atomic lines, and several transitions in the e6Pi-a6Delta transition of the FeH molecule. Spectra were recorded in laser excitation, with selective fluorescence detection. Magnetic field strengths varied from 4 to 7.2 kGauss. The atomic data yields improved Landé factors for Fe(I) levels. These are needed in turn to calibrate magnetic field accurately for the molecular Zeeman experiments. Data files are in Ascii format, with drawings of selected molecular lines (.png files), grouped according to spin component.
