摘要: We report spectroscopic measurements on the 6s6p 3P1 level of Lu+ at 28503.16 cm-1. The radiative lifetime this was measured to be 37.4 ± 1.9 ns using time-resolved laser-induced fluorescence a slow ion beam. Branching fractions were determined from Lu spectra recorded 1.0 m Fourier transform spectrometer National Solar Observatory. Thelog(gf) values by combining and branching for λ3507.39,λ 5983.90, λ6221.87 (air wavelengths) lines are - 1.16 0.03, 0.06, -0.76 0.04, respectively. Theλ 6221.87 line has been identified Bord, Cowley, Mirijanian (1997) as best candidate determination solar lutetium abundance because it is only slightly blended in spectrum. present transition probability measurement brings their into good agreement with CI chondrite abundance.
