    Abstract

    The existence and structure of positronic atoms with a total angular momentum of L=1 is studied with the configuration interaction method. Evidence is presented that there is a Po2 state of e+ Ca and Po 2,4 states of e+ Be (Po3) that are electronically stable with binding energies of 45 meV and 2.6 meV, respectively. These predictions rely on the use of an asymptotic series analysis to estimate the angular L? limit of the energy. Incorporating corrections that compensate for the finite range of the radial basis increased the binding energies of e+ Ca and e+ Be to 71 meV and 42 meV, respectively. � 2007 The American Physical Society.
