Abstract
At the LEAR facility, CERN, antiprotonic L alpha transitions in light eleme nts have been investigated with a focussing crystal spectrometer. The high resolution of the experiment allowed for the first time to resolve in (p) o ver bar H the 2(3)P(0) state from the close-lying states 2(3)P(2), 2(1)P(1) , and 2(3)P(1). In (p) over bar D the corresponding transitions were found to be more than an order of magnitude broader. To a large extent the result s for (p) over bar H support the meson exchange model.
