The hyperfine spectrum of 38-y207Bi in the 6 p34S3/2-6 p2(3P0)7 s4P1/2 3,067-Å resonance line was measured by absorption spectroscopy. The207Bi-209Bi isotope shift is 0.0999(20) cm-1. The relative isotope shifts in bismuth are found to follow the general pattern of the even-neutron number isotopes for the isotones with Z=80, 81, 82 and 87. The magnetic dipole and electric quadrupole hfs interaction constants for207Bi, A(4P1/2) =0.1630(3) cm-1 and B(4S3/2)=-0.016(3) cm-1, were obtained. Except for the isotope shift, these more precise values are in agreement with our previous results. © 1985 Springer-Verlag.
