Abstract

We study the inner structure of a positronium confined to a void by treating it as a two-particle quantum system where the electron is captured by an infinite potential well and the positron feels only the Coulomb attraction of the electron. We calculate the ground state and the related quantities that govern the annihilation rate, and discuss implications of the results.
