The magnetic moments and isotope shifts of the neutron-deficient francium isotopes 202-205Fr were measured at ISOLDE-CERN with use of collinear resonance ionization spectroscopy. A production-to-detection efficiency of 1% was measured for 202Fr. The background from nonresonant and collisional ionization was maintained below one ion in 105 beam particles. Through a comparison of the measured charge radii with predictions from the spherical droplet model, it is concluded that the ground-state wave function remains spherical down to 205Fr, with a departure observed in 203Fr (N = 116). ispartof: Physical Review Letters vol:111 issue:21 pages:212501-4 ispartof: location:United States status: published
