Abstract
Using the method of analytic continuation in the coupling constant with a model, we investigated the ground state of . In addition to a solution with the two valence neutrons in states (), we obtained a solution with the valence neutrons in states () as the ground state. Experimentally, such a state has not yet been observed. This newly predicted state of with the main component of corresponds to the ground state of with a halo structure.
