Abstract


We report measurements of the isotope shifts of the 3d(6)4s(2) a (5)D(4)-3d(6)4s4p z (5)F(5)(o) Fe I resonance line at 372 nm between all four stable isotopes (54)Fe, (56)Fe, (57)Fe, and (58)Fe, as well as the complete hyperfine structure of that line for (57)Fe, the only stable isotope having a nonzero nuclear spin. The field and specific mass shift coefficients of the transition have been derived from the data, as well as the experimental value for the hyperfine structure magnetic dipole coupling constant A of the excited state of the transition in (57)Fe: A(3d(6)4s4p z (5)F(5)(o)) = 81.69(86) MHz. The measurements were carried out by means of high-resolution Doppler-free laser saturated absorption spectroscopy in a Fe-Ar hollow cathode discharge cell using both natural and enriched iron samples. The measured isotope shifts and hyperfine constants are reported with uncertainties at the percent level.
