Abstract
We report the application of a new nonoptical detection scheme in laser spectroscopy on ion beams of on-line isotope separators. The method consists of ground-state depopulation by optical pumping in collinear laser-ion-beam interaction, state-selective neutralization, and charge-state-separated fast-atom counting. Strontium isotope-shift measurements are extended into the strongly deformed region of the neutron-rich isotopes up to . The radii are generally well described by the droplet model including empirical deformatins obtained from values.
