Towards laser spectroscopy in a supersonic gas jet at the S3 spectrometer (S3-LEB)

by Serge Franchoo

A new spectrometer S3 is presently under construction at Ganil. It will provide purified beams of medium-mass N=Z nuclei and heavy isotopes beyond actinium, both at the extremes of stability, at unprecedented intensities. As part of its instrumentation for nuclear physics at low energy (S3-LEB), a dedicated set-up for resonant laser ionisation and spectroscopy in a supersonic gas jet Reglis and a multi-reflection time-of-flight mass spectrometer Pilgrim are currently being commissioned.

With Reglis, ground and isomeric states of the extracted isotopes will be probed through laser spectroscopy in the expanding gas jet at low temperature and low density. By combining high efficiency and high spectral resolution, their shapes, sizes, spins and electromagnetic multipole moments can be measured. The prospective physics programme will bring within reach key nuclei such as 94Ag, 101Sn, or the isotopes of lawrencium. This contribution aims to cover the ongoing preparations.
