Configuration Interaction calculations of positron binding to Be(3Po)
arXiv:physics/0601053 · doi:10.1016/j.nimb.2006.01.037
Abstract
The Configuration Interaction method is applied to investigate the possibility of positron binding to the metastable beryllium (1s^22s2p 3Po) state. The largest calculation obtained an estimated energy that was unstable by 0.00014 Hartree with respect to the Ps + Be^+(2s) lowest dissociation channel. It is likely that positron binding to parent states with non-zero angular momentum is inhibited by centrifugal barriers.
