The NuSTAR HISPEC slowed down beams project at GSI/FAIR aims to produce rare isotopes with energies of 10 MeV/u and less, to be used for spectroscopy and reactions studies. The radioactive beams produced at the NuSTAR FAIR facility of sufficient intensity to perform Coulomb excitation, resonance or transfer reactions studies are included in the nuclear chart shown on Figure 1. There is limited or no information on the excited sates of many of these nuclei. The high production rates of slow down beams at FAIR will allow detail studies of these systems.
