Abstract
We performed high-resolution spectroscopy of Sm i in the near-UV transitions by using an extended-cavity violet diode laser. By adopting traditional Doppler-free saturated-absorption spectroscopy, we made accurate measurements of the isotope shifts for Sm i. For an atomic excitation laser we used an extended-cavity violet diode laser that was operated in the wavelength range 398–400 nm. As for the experimental results, Doppler-free spectra of the 399.002- and 399.102-nm transition lines of Sm were obtained and the isotope shifts between the even-mass isotopes were measured for the first time to our knowledge. Additionally, we used the King-plot method to check the consistency of the measured isotope shifts and to analyze them as mass shifts and field shifts. For a more quantitative analysis, we performed an ab initio calculation by using the relativistic multiconfiguration Dirac–Fock method.
