N2 - The velocity distribution of an ion beam from an IGISOL ion guide isotope separator on-line was measured directly by means of laser spectroscopy and compared with that estimated from the mass spectrum. The latter is found to be more than two times broader than the former. The emittance of the ion beam as well as its velocity spread was also studied with laser beams. It is noted that the emittance affects the mass spectrum considerably, resulting in a poor resolving power for the net velocity spread. Laser spectroscopy of radioactive atoms with the IGISOL, especially of refractory elements, seems promising.
