We have observed Lyman radiation from the muonic atoms formed when a beam of muons stops in a liquid hydrogen target. Energies for these X-rays lie in the range 1.9-2.5 keV. Our results are consistent with a ratio of Kα ΣK = 0.7 ± 0.2. In addition, we searched for X-rays from pionic hydrogen by stopping negative pions in liquid hydrogen. No clear evidence for pionic X-rays was found.
