title = "Search for p-nucleus states using the (p, p) knock-out reaction at 600 MeV/c",
abstract = "The knock-out reaction A(p, p)X has been used to search for narrow p-nucleus states. The experiment was performed using the 600 MeV/c antiproton beam at LEAR and the high-resolution and large-acceptance magnetic spectrometer SPES II. The A-dependence of the annihilation-induced proton spectra has been studied on 2H, 6Li, 12C, 63Cu, 208Pb and 209Bi. The quasi-free elastic pp scattering observed in the lighter targets, and the comparison with the free pp scattering, also observed in this experiment, determine an effective proton number Neff for 1s- and 1p-shell protons. No evidence for narrow bound or resonant p-nucleus states could be found. Upper limits for their production are one order of magnitude lower than certain theoretical predictions, but consistent with the properties of the p-nucleus interaction, as established from recent elastic and inelastic scattering as well as from studies of antiprotonic atoms.",

note = "Funding Information: The search for p-nuclear states formed by an antiproton and a nucleus, which are different from the well-known antiprotonic atom states bound by the Coulomb interaction, was made possible at the CERN low-energy antiproton ring (LEAR) with the availability of intense, pure, high-resolution antiproton beams. The favourable conditions for such states to exist are that the l~-nucleus interaction, described * Supported in part by the Fund for Basic Research of the Israel Academy of Sciences.",
