摘要：

He-2 is examined in the second state of the 3 Pi(g) symmetry. This state is shown to be one of the two ''parent'' states of the lowest known stable negative ionic He-2(-) state of the 4 Phi(g) symmetry. It is compared with the other parent neutral He-2 state, which is the lowest of the 3 Delta(u) symmetry, with a consequence that the negative ionic state be a closed channel resonance with respect to both of its neutral parent states. Furthermore the third He-2 3 Pi(g) and the second He-2 3 Delta(u) states are shown to be the parents of the second He-2(-) 4 Phi(g) resonance.
