Description
A low-energy Coulomb excitation experiment which employed 106,108Sn radioactive ion beams was recently performed at the ReA6 facility of FRIB. The experiment utilized the SeGA-JANUS setup for coincident particle and gamma ray detection. The measurement, its motivation, and the experimental results will be presented. In particular, results on B(E2) transition strengths and previously-unknown Qs spectroscopic quadrupole moments will be shown. These results advance our understanding of shape and collectivity in an area of the nuclear chart very close to doubly-magic 100Sn.
This work was performed under the auspices of the US Department of Energy by Lawrence Livermore National Laboratory under Contract No. DE-AC 52-07NA27344.
