Traveling beyond the neutron dripline with MoNA

The study of the nuclear structure across the nuclear chart was recently proven to be much more exciting than originally thought. Although most stable nuclei are believed to be well understood, as we move further away from the valley of stability and toward the proton and neutron driplines the evolution of the nuclear shells reveals unexpected phenomena. New magic numbers and halo structures are just a few examples of the surprises that exotic nuclei have to show. The investigation of these phenomena is experimentally challenging, mainly due to the fact that the available beam rates are rather low. On top of that, getting close to the neutron dripline one has to deal with the fact that several excited (or even ground) states are neutron unbound. An experimental system suitable for the study of neutron-­unbound states is the MoNA/Sweeper setup, located at the National Superconducting Cyclotron Laboratory at Michigan State University. Recent results from measurements with the MoNA/Sweeper setup will be presented and the implications to the nuclear structure along the neutron dripline will be discussed.
