1999Sa06: Unstable to ground state neutron emission. Reaction: Ta(40Ar,x), E=94.1 MeV/nucleon, at RIKEN facility. Magnetic fragment separator, identification by measurements of energy loss, time-of-flight, magnetic rigidity for each fragment, etc. No 30F events were identified. Similar results were reported in 2004Lu19.
Structure calculation:
2022Fo03: Performed large-scale shell model calculations including continuum states to investigate the properties of the neutron-rich isotopes of fluorine. Predicted the occupancy and role of the νp3/2 shell of the heaviest fluorine isotopes including 30F.
