| Abstract: | Theoretical Hartree-Fock calculation are summarized for the X=e+] systems with X = O, S, Se, and Te which establish the stability of bound states for the system. The two-photon annihilation lifetime, τ, and angular correlation, N(θ), are calculated and positron annihilation from alkaline earth oxides is discussed. |
