In-gas-cell laser resonance ionization spectroscopy of ^{200, 201}Pt

NUCLEAR MOMENTS ^198,200,201Pt; measured time-of-flight (TOF) spectra for ions with mass-to-charge-ratios, laser resonance ionization spectra using Multireflection time-of-flight mass spectrograph (MRTOF-MS) at KEK Isotope Separation System (KISS) of RIKEN facility. ^200,201Pt; deduced differential mean-square charge radii and isotope shifts relative to those of ¹⁹⁸Pt, magnetic dipole and electric quadrupole moments of ²⁰¹Pt, β₂ deformation parameters Comparison with theoretical calculations using symmetry-conserving configuration-mixing (SCCM) with Gogny D1S energy density functionals (SCCM+Gogny D1S), finite-range droplet model (FRDM), and constrained-Hartree-Fock-Bogoliubov (CHFB) theory with five-dimensional collective Hamiltonian (5DCH) based on the Gogny D1 interaction. ²⁰¹Pt; deduced most likely spin-parity of 5/2-. ^198,200,201Pt produced in ¹⁹⁸Pt(¹³⁶Xe, X), E=10.75 MeV/nucleon multi-nucleon transfer reactions.
