摘要：

The hyperfine structure of the 5d6s (2) D-2(3/2) -> 5d6s6p F-4(5/2) transition of the radioactive isotope Lu-177 has been investigated by laser photoionization spectroscopy. Measured spectra permitted the determination of hyperfine magnetic dipole constants and electric quadrupole constants for ground and excited state as well as the isotope shift of the Lu-177 isotope. The data obtained were used to confirm the selective photoionization of Lu-177 from a neutron-irradiated sample that initially had a natural isotope composition. A concentration for Lu-177 of 50 % was achieved, and the photoionization efficiency was estimated as suitable for technological application.
