    Abstract

    Laser spectroscopy has been used to obtain a definitive nuclear spin assignment, I = 9/2, for 31.5-y 207Bi. For such a large spin the value obtained from previous hfs measurements at zero magnetic field was subject to uncertainty. The Zeeman pattern of the 6p3 4S3/2 - 6p27s 4P 1/2 306.7-nm resonance line was studied at a magnetic field of ≈ 0.75T to yield the result. The spectrum was detected by the observation of the 6p27s 4P 1/2 - 6p3 2D3/2 fluorescence at 472.2 nm. A comparison of Doppler-broadened spectra obtained by laser-excited fluorescence spectroscopy and those by dispersive spectroscopy put in evidence the additional effect of the diffraction-grating instrument function.
