Abstract

The positive-paxity state problem in ^<10>Li, which is a key of understanding the halo structure in ^<11>Li, is discussed based on the idea of the Pauli-blocking effect on the valence p_<1/2>-neutron due to the neutron J^π = 0^+ pairing configuration mixing in the ^9Li core. A scenario of how the energetical degeneracy of S_<1/2>-and p_<1/2>-orbits happens is explained in detail.
