Sažetak
The very neutron-rich oxygen isotopes 25 O and 26 O are investigated experimentally and theoretically. The unbound states are populated in an experiment performed at the R3B-LAND setup at GSI via proton-knockout reactions from 26 F and 27 F at relativistic energies around 442 and 414 MeV/nucleon, respectively. From the kinematically complete measurement of the decay into 24 O plus one or two neutrons, the 25 O ground-state energy and width are determined, and upper limits for the 26 O ground-state energy and lifetime are extracted. In addition, the results provide indications for an excited state in 26 O at around 4 MeV. The experimental findings are compared to theoretical shell-model calculations based on chiral two-and three-nucleon (3 N) forces, including for the first time residual 3 N forces, which are shown to be amplified as valence neutrons are added.
