Abstract

The stability and other properties of the dipositronium molecule are discussed. It is pointed out that the dipositronium binding energy may be explained on the basis of a simplified model which satisfies the important requirement of providing a consistent description of the “atoms” and “molecule” of positronium. The importance of correlations in positronium and dipositronium is analyzed. In comparing positronium and dipositronium with atomic and molecular hydrogen, a remarkable parallelism is identified but also significant differences.
