Description
EXL (EXotic nuclei studied in Light-ion induced reactions) is a project within NUSTAR at FAIR that aims to investigate nuclear structure at storage rings with direct reactions in inverse kinematics. The programme is focused on reactions with very low momentum transfers. The existing storage ring ESR at GSI provides a unique opportunity to perform part of the programme already now. We successfully performed experiments with stable 20Ne and 58Ni as well as radioactive 56Ni beams at energies from 50 - 400 MeV/u hitting the internal gas jet target. The target recoils were measured by a newly developed UHV compatible Si detector setup.
The first physics goal was to deduce the nuclear matter radius of 56Ni from elastic proton scattering at 390 MeV/u. This experiment can be considered as the first successfully observed nuclear reaction with a stored radioactive beam ever. As proof of principle experiment, in inelastic scattering the excitation of the isoscalar giant monopole resonance in 58Ni was observed.
In my talk, I present the status of the project and discuss the opportunities at FAIR and with the TSR at HIE-ISOLDE.
