We present the results of high-resolution laser spectroscopy of the long-lived radioactive isotopes 143 - 147 Pm. The hyperfine structures and isotope shifts in two different atomic ground-state transitions at 452 nm and 468 nm were probed by in-source laser spectroscopy at the RISIKO mass separator in Mainz, using the PI-LIST ion source. From the hyperfine coupling constants the nuclear magnetic dipole and electric quadrupole moments for 143 - 147 Pm were derived, and the measured isotope shifts allowed the extraction of changes in nuclear mean square charge radii.
