Study of a Selective Photoionization Scheme of 177Lu

详细

The hyperfine structure of transitions in the three-step scheme 5d6s²²D_3/2–5d6s6p⁴F\(_{{5/2}}^{^\circ }\)–5d6s7s⁴D_3/2– (53 375 cm^–1)\(_{{1/2}}^{^\circ }\) of lutetium ionization is studied for ¹⁷⁵Lu, ¹⁷⁶Lu, and ¹⁷⁷Lu isotopes using the photoionization laser spectroscopy method. Values of the magnetic dipole (A) and electric quadrupole (B) interaction constants are determined, as well as the energies, the isotope shifts, and the radiative lifetimes for the 5d6s7s⁴D_3/2 and (53 375 cm^–1)\(_{{1/2}}^{^\circ }\) levels.
