Existence of a Po2 excited state for the e+Ca system

Michael Bromley, James Mitroy

Research output: Contribution to journal › Article › peer-review

Abstract

The configuration interaction method is used to demonstrate that there is an electronically stable state of positronic calcium with an orbital angular momentum of L=1. This prediction relies on the use of an asymptotic series to estimate the variational limit of the energy. The best estimate of the binding energy is 37meV. A discussion of the structure of the system is also presented. � 2006 The American Physical Society.
