Precision mass measurement of n-deficient cadmium isotopes at ISOLTRAP — •Christoph Schweiger for the ISOLTRAP collaboration — Max-Planck-Institut für Kernphysik, Heidelberg, Germany
Isoltrap [1] is a multi-ion-trap mass spectrometer located at ISOLDE/CERN dedicated to high-precision mass measurements of artificially produced, short-lived, exotic radionuclides far from stability.
Experimentally, Isoltrap employs multi-reflection time-of-flight and Penning-trap mass spectrometry techniques for direct mass measurements.
Following the mass-energy equivalence, the measured masses can be related to nuclear binding energies, reflecting the underlying interactions and structure in the nucleus.
Knowledge of the binding energies therefore allows the study of nuclear structure and nuclear astrophysics.
To this end mass filters are employed.
In addition, precision mass data have applications in fundamental physics such as neutrino or weak interaction studies.
Following an introduction of the experimental setup, recent mass measurements of neutron-deficient cadmium isotopes in vicinity of the self-conjugate doubly-magic 100Sn will be presented.
The contribution will also include technical developments that improved the experimental setup significantly.
