Isotope shifts and hyperfine structures have been measured on the 306.7 nm
line in bismuth isotopes with A = 205-210, 210m, 212 and 213 by gas cell la
ser spectroscopy. More precise measurements were made for the A = 207-209 i
sotopes in atomic beam measurements. Nuclear magnetic and quadrupole moment
s were deduced. A detailed comparison of the nuclear charge radii systemati
cs has been made in the region using a King plot technique.
