Short-Range Correlations in neutron-rich nuclei — •Meytal Duer — TU Darmstadt, Darmstadt, Germany

When nucleons come in close proximity they experience the short-range part of the nucleon-nucleon interaction. These states are referred to as Short-Range Correlated (SRC) nucleon-nucleon pairs, with large relative momentum and small cente-of-mass momentum with respect to the Fermi momentum. SRC pairs are formed as temporary fluctuations with high density, several times the nuclear saturation density. These are densities that exist in neutron stars, but are difficult to study in the lab.

Most of the knowledge we have to date about SRC comes mainly from electron scattering experiments. These demonstrated that at any given moment, about 20% of the nucleons in nuclei are members of such neutron-proton SRC pairs. Electron scattering experiments are limited, however, to stable nuclei. To overcome this limitation, to access very neutron-rich nuclei, radioactive-ion beams are the only way to do so. The next generation of proposed experiments includes the use of hadronic probes in inverse kinematics.

Our recent experiment at JINR, Russia showed for the first time that SRC pairs are accessible in inverse kinematics. This showcases a new ability to study SRC in short-lived exotic nuclei at the R3B setup at GSI and in the future at FAIR. The first experiment with radioactive nucleus, 16C, will be performed at R3B in 2022. A successful experiment will pave the way for systematic studies of the neutron excess for example along isotopic chains.
