Abstract : A search for 28O with a 78 AMeV beam of the neutron-rich isotope 36S has been performed for the first time. Evidence for the unbound character of 28O was obtained. In the same experiment the half-lives of the very neutron-rich isotopes 27,29F and 30Ne were measured and those for 28,29Ne and 30,31Na reexamined. The results are compared to shell-model predictions and conclusions drawn regarding the extent of the region of deformation around N = 20.
