Nuclear structure studies in the area around the valence maximum of 170Dy with CLARA + PRISMA — •Pär-Anders Söderström — Uppsala University

While the existence of shell closures and the search for exotic “doubly magic” nuclei is a cornerstone of our understanding of the atomic nucleus, their even-even, “doubly-mid-shell” counterparts are arguably even more rare. Above the sd shell, the corresponding doubly mid-shell, even-even systems which are particle bound are limited to 28Si, 38Si, 48Cr and 170Dy. Assuming the standard spherical shell gaps, 170Dy might naively be expected to be amongst the most collective of all nuclei. The double mid-shell at 170Dy may also represent the single best hope in the entire Segré chart for the empirical realization of the SU(3) dynamical symmetry of the interacting boson model.

An experiment for nuclear structure studies of 170Dy and its neighbors has been performed at Laboratori Nazionali di Legnaro. Multi-nucleon transfer reactions with a 82Se beam on a 170Er target were used to reach the neutron-rich isotopes. The reaction fragments were identified using the magnetic spectrometer PRISMA and the gamma-ray spectra were recorded using the CLARA germanium detector array. The analysis of this data is ongoing. Preliminary gamma-ray spectra for neutron rich isotopes in this area will be presented as well as relative cross sections for production of these isotopes in multi-nucleon transfer reactions.
