Abstract

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.
