The Collinear Resonance Ionization Spectroscopy (CRIS) experiment is a laser spectroscopy setup operating at the ISOLDE facility of CERN, allowing to study the evolution of fundamental properties of the ground state (spin, electromagnetic moments and charge radii) as function of the neutron number. In 2022, the CRIS collaboration undertaken an experimental campaign aiming at the study of nuclear structure evolution along the Al and Ag chain, together with the first experimental study of the AcF radioactive molecule. The neutron-rich Al isotopes provide an excellent opportunity to investigate the evolution of nuclear structure crossing the N = 20 shell closure and the transition into the N=20 island of inversion. The Ag isotopes, with three proton holes in the Z=50 shell closure, are an ideal case to investigate the structural evolution approaching the N=50 and N=82 subshell closure, in the vicinity of 100Sn and 132Sn. Furthermore, when compared to the Z=49 In isotopes, the study of Ag isotopes allows to pin down the effect of additional proton holes on the electromagnetic properties of the ground state. During this presentation, the preliminary results of these experiments will be presented together with the prospects of the CRIS experiment for 2023.
The SPIRAL2/S3 facility will offer new opportunities for laser spectroscopy studies, allowing to explore regions of the nuclear chart which have not been studied yet with this technique. The measurement of the electromagnetic properties of the ground state in three regions of interest will be discussed. Finally prospects of laser spectroscopy campaigns at S3-LEB and at DESIR with a new versatile high-resolution laser spectroscopy setup will be presented.
