Beams of pp̄ atoms flighting in vacuum with adjustable velocity have been proposed to study the spectroscopy of protonium atoms with high energy resolution (Ae/E down to 10-5) by using differential absorber foils and conventional X-ray detectors for emission spectroscopy and fixed frequency high power radiation sources for induced spectroscopy1. This aproach would lead to an improvement by more than two orders of magnitude versus the possibilities of “conventional” experiments in the field of protonium planned at LEAR2, and would give ways to measure with high accuracy effects of electromagnetic and strong interactions on the atomic levels of protonium.
