Abstract :
The binding of at least six additional neutrons of fluorine compared to oxygen is linked to the emergence of the N = 16 shell close to the dripline. Single proton knock-out reactions from neutron-rich fluorine isotopes on a 12C target were measured at energies of ∼50 MeV/nucleon. Oxygen isotopes of A = 19 – 24 were observed. The particle instability of 25O was confirmed.
