Abstract
The hyperfine spectrum of 38−y 207Bi in the 6p 3 4 S 3/2−6p 2(3 P 0)7s 4 P 1/2 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 withZ=80, 81, 82 and 87. The magnetic dipole and electric quadrupole hfs interaction constants for207Bi,A(4 P 1/2) =0.1630(3) cm−1 andB(4 S 3/2)=−0.016(3) cm−1, were obtained. Except for the isotope shift, these more precise values are in agreement with our previous results.

Dedicated to Prof. Dr. A. Steudel on the occasion of his 60th birthday
We should like to dedicate this article to Professor Andreas Steudel on the occasion of his sixtieth birthday. His contribution to isotope shift research has been stimulating to us for over one quarter of a century! We are grateful to Dr. Philip E. Horwitz, Argonne National Laboratory, for his help with the radiochemistry. We owe a debt of gratitude to Dr. Jerry Lerner (deceased), A.N.L., for many years of invaluable assistance with our mass separations. The contributions of Dr. Carlos A. Mariño to the early part of this work is also acknowledged. We appreciate the continued support of the Princeton University Cyclotron group.
