Abstract:

The 9Li-n interaction is discussed based on the idea of the Pauli blocking for the Jπ=0+ neutron pairing correlation in the 9Li core due to the presence of the last valence neutron. The present studies are developed in a framework of the microscopic coupled-channel model for {9Li((0p3/2)4ν) + n} + {9Li((0p3/2)2ν(0p1/2)2ν) +n} + {9Li((0p3/2)2ν(1s0d)2ν) +n}. The channel of the present model consists of the last valence neutron coupled with a 9Li configurational state connected by the Jπ=0+ pairing interaction. Due to the presence of the valence neutron in the 0p1/2 orbital, the (0p3/2)2→(0p1/2)2 jump in the 9Li core is prevented. Thus, the p1/2-orbital neutron states experience a strong repulsive effect due to the lack of the configuration mixing between (0p3/2)4ν and (0p3/2)2ν(0p1/2)2ν, and its energy rises up significantly. In contrast to this, the sd-orbital neutron imparts a very weak effect on the configuration mixing. As a result, the s1/2-orbital state is obtained in the vicinity of the threshold as a bound state or virtual resonance for the 9Li-n interaction which reproduces 1+(Sn=-0.42 MeV) and 2+(Sn=-0.82 MeV) states consistently with experimental data observed by Bohlen et al. The effective 9Li-n potential which has the strong parity dependence deduced from the present coupled-channel calculation is discussed to be very promising for studying the halo structure of 11Li within the 9Li + n + n model.
