Doubly-magic character of ¹³²Sn studied via electromagnetic moments of ¹³³Sn

NUCLEAR MOMENTS ¹³³Sn; measured hyperfine structure spectra, magnetic dipole moment (μ) and electric quadrupole moment (Q) using high-resolution collinear laser spectroscopy at ISOLDE-CERN facility; deduced 1f_7/2 neutron orbital configuration for ¹³³Sn g.s., and doubly-magic character of ¹³²Sn. ¹³³Sn activity produced in fission of a uranium carbide target by neutrons from spallation reaction on tungsten by high-energy protons, followed by laser ionization and mass selection through a linear Paul trap. Systematics of magnetic dipole moments (μ) and electric quadrupole moments (Q) for N=83 isotones: ¹³³Sn, ¹³⁵Te, ¹³⁷Xe, ¹³⁹Ba, ¹⁴¹Ce, ¹⁴³Nd, ¹⁴⁵Sm, ¹⁴⁷Gd and ¹⁴⁹Dy. Comparison with shell-model calculations.
