High-precision mass measurements near Sn-100 challenge nuclear theory — •Lukas Nies for the ISOLTRAP collaboration — CERN, 1211 Geneva, Switzerland — Universität Greifswald, Germany

Nuclear binding energies arise from various effects that govern nuclear properties. Different nucleon configurations within nuclear isomers lead to modified binding energies, often resulting in mass differences of tens to hundreds of kilo-electronvolts. These isomeric excitation energies can be directly accessed by measuring the difference in atomic masses of ground and isomeric states. In this contribution, high-precision mass measurements of ground and isomeric states in tin, indium, and cadmium isotopes near tin-100 using the multi-reflection time-of-flight technique will be presented and compared to nuclear theory.
