In-gas-cell laser resonance ionization spectroscopy of ^{196, 197, 198}Ir

NUCLEAR MOMENTS ^196,197,198Ir; measured hyperfine structure (HFS) spectra using in-gas-cell laser resonance ionization spectroscopy at the KEK Isotope Separation System at RIBF-RIKEN facility; deduced spins for the ground states, magnetic dipole moments, mean-square charge radii, isotope shifts, β₂ deformation parameters. Comparison with theoretical calculations based on the strong coupling model. Comparison with previous experimental results. Systematics of quadrupole moments, magnetic dipole moments, mean-square charge radii and β₂ deformation parameters for ^{189,191,193,196,197,198}Ir.

NUCLEAR REACTIONS ¹⁹⁸Pt(¹³⁶Xe, X)¹⁹⁶Ir/¹⁹⁷Ir/¹⁹⁸Ir, E=10.75 MeV/nucleon; measured extraction yields, Eβ, half-lives of the decays of ¹⁹⁶Ir, ¹⁹⁷Ir and ¹⁹⁸Ir. The Ir isotopes produced in multi-nucleon transfer reaction. Comparison with previous experimental half-lives.
