摘要/Abstract

摘要： Hyperfine structure spectra of singly ionized lanthanum and praseodymium have been measured by collinear fast-ion-beam laser spectroscopy. All the spectral lines were resolved and the magnetic dipole and electric quadruple coupling constants of the metastable levels and excited levels were determined. Our results are in agreement with the published data within the experimental uncertainty. For praseodymium ions, the accuracy of the magnetic dipole coupling constants are improved by one order of magnitude compared with other published data, and the electric quadruple coupling constants are reported for the first time.
