Аннотация:The hyperfine structure of transitions of the three-step photoionization scheme of lutetium, 5d6s(2) D-2(3/2)-5d6s6p F-4-5d6s7s D-4(3/2)-(53 375 cm(-1)), for Lu-177m nuclear isomer has been investigated for the first time by laser resonance photoionization mass spectroscopy. Hyperfine-splitting constants, energy levels, and magnetic dipole and electrical quadrupole moments of the Lu-177m nucleus are determined. Isotope shifts of the isomer spectral lines relative to natural isotopes and Lu-177 have been investigated.
