In-gas-cell resonance laser ionization has been performed on long-lived isotopes of Pu at the IGISOL facility, Jyvaskyl ¨ a. This ¨
initiates a new programme of research towards high-resolution optical spectroscopy of heavy actinide elements which can be
produced in sufficient quantities at research reactors and transported to facilities elsewhere. In this work a new gas cell has been
constructed for fast extraction of laser-ionized elements. Samples of 238−242Pu and 244Pu have been evaporated from Ta filaments,
laser ionized, mass separated and delivered to the collinear laser spectroscopy station. Here we report on the performance of the
gas cell through studies of the mass spectra obtained in helium and argon, before and after the radiofrequency quadrupole coolerbuncher.
This provides valuable insight into the gas phase chemistry exhibited by Pu, which has been additionally supported by
measurements of ion time profiles. The resulting monoatomic yields are sufficient for collinear laser spectroscopy. A gammaray
spectroscopic analysis of the Pu samples shows a good agreement with the assay provided by the Mainz Nuclear Chemistry
department.
