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 laser spectroscopy. More precise measurements were made for the A = 207-209 isotopes in atomic beam measurements. Nuclear magnetic and quadrupole moments were deduced. A detailed comparison of the nuclear charge radii systematics has been made in the region using a King plot technique.

Isotope shifts and hyperne structures of the 205;206;208;210;210m;212;213 Bi isotopes have been studied on the 306.7nm line using gas cell laser spectroscopy. The neutron{ rich isotopes are the rst isotones of Pb to be measured immediately above the N=126 shell closure. The ground state quadrupole moments of the even{N isotopes increase as neutrons are added or removed from the N=126 shell, but no corresponding increase is observed in the charge radii.

At the Jyv~kyl~i IGISOL facility, different ion guide designs are used for different types of reactions. The performance of these ion guides is summarized. The limitations for performing nuclear decay studies and collinear laser spectroscopy due to the large beam energy spread and the presence of isobars will be removed after the installation of an ion beam cooler to reduce the energy spread and a longitudinal penning trap for performing isobaric mass separation. These new developments will bring the capabilities of the IGISOL facility to a new level.
