文摘

In-gas-cell laser ionization spectroscopy studies on the neutron deficient ^97-101Ag isotopes have been performed with the LISOL setup. Magnetic dipole moments and mean-square charge radii have been determined for the first time with the exception of ¹⁰¹Ag, which was found in good agreement with previous experimental values. The reported results allow tentatively assigning the spin of ^97,99Ag to and confirming the presence of an isomeric state in these two isotopes, whose collapsed hyperfine structure suggests a spin of . The effect of the shell closure is not only manifested in the magnetic moments but also in the evolution of the mean-square charge radii of the isotopes investigated, in accordance with the spherical droplet model predictions.
