Multi-Coincidence Spectroscopy of SHE using TASISpec — •Lise-Lotte Andersson — Helmholtz-Institut Mainz
The isotope 253No was produced in the two neutron evaporation channel using the 48Ca + 207Pb reaction. The structure of both mother and daughter nuclei was studied with TASISpec [1], a compact spectroscopy set-up placed in the focal plane of the gas-filled separator TASCA at GSI, Darmstadt. TASISpec allows for multi-coincidence spectroscopy including correlations between implanted nuclei, α particles, electrons, X- and γ rays. For example, electron lines originating from internal conversion can, for the very first time, be observed in the Si-strip box detectors at the same time as γ-rays are observed in the surrounding Ge detectors. This is a unique strength of TASISpec, which here provides the possibility to determine the multipolarities of these transitions, using conversion coefficient systematics.
Results from experimental studies will be presented together with GEANT4 simulations of the setup and theoretical predictions of the nuclear structure.
