Description
With a proton hole in the Z = 50 shell closure, the indium isotopic chain (Z = 49) offers a
compelling scenario to explore the evolution of nuclear-structure properties in the
neighbourhood of the doubly-magic isotopes 100Sn (Z, N = 50) and 132Sn (N = 82).
This contribution will present recent measurements of the hyperfine spectra of the neutronrich
indium isotopes 113-131In using the Collinear Resonance Ionization Spectroscopy
(CRIS) experiment. From these measurements, the spins, electromagnetic moments, and
changes in root-mean-squared charge radii of several ground and isomeric states have been
determined for the first time, extending our experimental knowledge up to N = 82. The
importance of these results, in connection with modern developments of nuclear theory,
will be discussed.
The development of the ionization schemes used during the experiment was enabled by the
creation of an ablation ion-source setup, which will also be discussed
