The in-gas laser ionization and spectroscopy (IGLIS) technique was applied on the 212–215Ac isotopes, produced
at the Leuven Isotope Separator On-Line (LISOL) facility by using the in-gas-cell and the in-gas-jet methods.
The first application under on-line conditions of the in-gas-jet laser spectroscopy method showed a superior
performance in terms of selectivity, spectral resolution, and efficiency in comparison with the in-gas-cell method.
Following the analysis of both experiments, the magnetic-dipole moments for the 212–215Ac isotopes, electricquadrupole
moments and nuclear spins for the 214,215Ac isotopes are presented and discussed. A good agreement
is obtained with large-scale nuclear shell-model calculations by using a 208Pb core.
