Probing the O(6) character of 196Pt with inelastic electron scattering — •Simela Aslanidou, Andreas Krugmann, Peter von Neumann-Cosel, and Norbert Pietralla — Institut für Kernphysik, Technische Universität Darmstadt
The Interacting-Boson-Model [1] provides an elegant tool to classify low lying collective states in medium and heavy mass even-even nuclei. One of its dynamical symmetries is O(6) and a crucial test of this theory is to investigate the monopole transitions to the band head of the K=0 , σ=N-2 band.
A powerful tool to investigate monopole transitions is inelastic electron scattering. An experiment on 196Pt -claimed to be a perfect O(6) nucleus [2]- has recently been performed at the superconducting electron linear accelerator S-DALINAC at Darmstadt using the high resolution LINTOTT spectrometer.
The experiment and preliminary results will be presented.
