Measurement of hyperfine structure spectrum in 569.08 nm line of 141Pr+

Hyperfine structure spectrum in 569 08nm line of 141 Pr + was measured by the collinear fast ion beam laser spectroscopy. All the spectral lines were resolved. The magnetic dipole and electric quadruple coupling constants, and hyperfine splitting of the metastable levels and excited levels were determined. Our results were in agreement with the published data within experiment uncertainty. The accuracy of the magnetic dipole coupling constants was improved by one order of magnitude compared with the published data.
