Abstract

The status of theoretical and experimental investigations on unbound nucleus()~(9)He is briefly introduced. The results of modern shell model suggest that the ground state of~(9)He should be 1/2~(+) instead of 1/2~(- )as expected by the normal shell ordering. Therefore, it means that the parity inversion which was well known in~(11)Be occurs also in~(9)He ground state. Recently, some resonance states were observed in transfer reactions and final-state reaction, but their spin-parities cannot be exact...
