Exploring the nuclear landscape with laser-spectroscopy techniques

by Dr Magdalena Kowalska (CERN)

Monday 19 Nov 2007, 16:30 → 17:30 Europe/Zurich

500/1-001 - Main Auditorium (CERN)

In this talk I will present recent results from the COLLAPS experiment located at ISOLDE/CERN, which uses laser spectroscopy techniques to probe ground state properties of exotic nuclei, with very high or low N/Z ratios and short lifetimes. By optically exciting or pumping atoms or ions with laser light we can measure nuclear spins, magnetic dipole and electric quadrupole moments, as well as charge radii. Recent results include the magnetic moment and spin of ³¹Mg and ³³Mg (N/Z around 1.7) and the quadrupole moment of the halo nucleus ¹¹Li (N/Z=2.67). These measurements are very valuable for exploring the nuclear shell structure far from stability or locating regions of deformations and revealing the nature of nuclear halos. The accurate values of nuclear ground-state observables help to test current nuclear models and improve the understanding of strongly interacting systems at the femtometer scale.

* Tea & coffee will be served at 16:00.
