Abstract : We describe an experimental method which will enable one to establish the chemical stability and measure the binding energies of compounds containing positronium atoms. The method consists of crossing a monoenergetic beam of very low energy 1 - 25 eV positrons with a supersonic expansion molecular beam, and detecting a signature ion while measuring its kinetic energy. Except for the use of a positron beam instead of an electron beam, this is conventional MS-IKES mass spectrometry-ion kinetic energy spectrometry, and the process involved is dissociative attachment.
