Abstract
The shell structure of low-lying neutron resonance levels in axially symmetric quadrupole-deformed potentials is discussed, which seems analogous to that of weakly bound neutrons. As numerical examples, nuclei slightly outside the neutron drip line, and , are studied. For the lowest resonance I obtain for which is likely to be prolately deformed, while may be assigned to the nucleus which may be oblately deformed. Consequently, will not be observed as a recognizable resonance state, in agreement with the experimental information.
