Description
K and L series X-rays have been observed from panti 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 Ksub(α) energy of 8.9+-0.3 keV, corresponding to a strong interaction shift of (-0.5+-0.3) keV. (orig.)
