The neutron drip line up to fluorine has been investigated by the projectile fragmentation of a 94.1 A MeV Ar beam at the fragment separator RIPS at RIKEN. A new neutron-rich isotope, F, has been observed for the first time while clear evidence for the particle instability of 24,25N, 27,28O and 30F has been obtained. The sudden change in stability from oxygen to fluorine may demonstrate the onset of deformation for the neutron-rich fluorine isotopes.
