Abstract The wave function of a positron in ReO3 is calculated using the augmented-plane-wave method. Due to the loosely-packed structure of ReO3, the ground-stateГ 1 wave function exhibits a marked anisotropy particularly around the oxygen ions, and a large fraction of a positron is distributed in the interstitial region. Experimental results of the positron annihilation 2γ correlations and the positron annihilation rates in ReO3 are discussed based on the positron wavefunction.
