Abstract
The annihilation of positrons in a simulated interstellar medium consisting of molecular hydrogen and a small admixture of the polycyclic aromatic hydrocarbon, naphthalene, was studied in a Penning trap containing cold positrons. The experiments demonstrate the ability to distinguish two distinct components in the annihilation γ-ray spectra. The significance of the experiment for the analysis of γ-ray spectra of astrophysical origin is discussed.
