Abstract

Lyman and Balmer transitions of antiprotonic hydrogen and deuterium have been measured at the Low-Energy Antiproton Ring LEAR at CERN in order to determine the strong-interaction effects. In LEAR experiment PS207, the X-rays were detected using Charge-Coupled Devices (CCDs) and a reflection-type crystal spectrometer. A complete set of strong-interaction parameters for the 1 s and the 2 p levels is now available for both \( \bar pH{\mathbf{ }}{\text{and}}{\mathbf{ }}\bar pD \) after evidence was found for the \( \bar pD{\mathbf{ }}{\text{K}}\alpha \) transition.
