Collinear Resonance Ionization Spectroscopy of Neutron-Rich Indium Isotopes

Zusatztext

This thesis describes the application of the collinear resonance laser spectroscopy to sensitively measure the electromagnetic nuclear observables of the neutron-rich indium isotopes <sup>115-131</sup>In. This entailed a systematic study of the efficiency of resonant ionization schemes to extract the hyperfine structure of the isotopes, the atomic charge exchange process and benchmarking of modern atomic calculations with a laser ablation ion source. <p>This allowed determination of the root-mean-square nuclear charge radii, nuclear magnetic dipole moments, nuclear electric quadrupole moments and nuclear spins of the <sup>113-131</sup>In isotopes with high accuracy. </p><p>With a proton hole in the Z = 50 nuclear shell closure of tin and several nuclear isomer states, these measurements of the indium (Z = 49) isotope chain provided an efficient probe of the evolution of nuclear structure properties towards and at the doubly-magic nuclear shell closure of <sup>132</sup>Sn (N = 82) - revealing unpredicted changes.</p>
