A change of the intensity of resonance fluorescence may take place when Zeeman states of the excited level have the same energy. The fields at which these `level crossings' occur in 199Hg and 201Hg have been measured. Combined with recent determinations of the hyperfine coupling constants, the results yield values for gJ of the 3P1 states: gJ (199)=1.48634±0.00005, gJ (201)=1.48606±0.00015.
