Popis: K and L series X-rays have been observed from p p atoms formed in hydrogen gas at NTP in association with annihilations into neutral particles. The total K X-ray yield is (6.5 ± 3.2) × 10−3 per stopped antiproton. A model-dependent fit of the K X-ray spectrum gives a Kα energy of 8.9±0.3 keV, corresponding to a strong interaction shift of (−0.5±0.3) keV.
