Understanding the nucleus and its structure relies on exploring the ground-state properties of nuclei far from stability. Many of these properties, such as the spin, nuclear electromagnetic moments and charge radii, can be measured with laser spectroscopy in a model-independent way. On-line laser spectroscopy provides access to these properties of long-lived states (>10ms). One region of interest is between the strongly deformed zirconium (Z=40) and the nearly-spherical tin (Z=50). This region features many competing configurations with rich isomerism and thus has been of central interest in recent experiments: tin [1], indium [2], cadmium [3], palladium [4] and neutron-deficient silver [5-6] have been successfully studied. Recently, neutron-rich silver has been investigated at IGISOL [7-8] in Jyväskylä and at ISOLDE/CERN [9] with the newly implemented voltage scanning at CRIS.
I will present the results of the recent CRIS experiment on silver in parallel with the IGISOL results. The spins and nuclear electromagnetic moments of the ground-state and multiple long-lived isomers have been deduced. This data provides a benchmark and challenge to state-of-the-art nuclear models in this region. Moreover, I will present a comparison of laser scanning and voltage scanning performed at CRIS, showcasing the strength of voltage scanning in collinear laser spectroscopy.
