Interaction of antiprotons with nuclei

Popis výsledku v původním jazyce

We report on self-consistent calculations of anti-p quasi-bound states in selected nuclei performed within the relativistic mean-field (RMF) model employing anti-p coupling constants tuned to reproduce anti-p-atom data. We confirmed considerable polarization of the nuclear core induced by the antiproton. The anti-p annihilation was treated dynamically, taking into account the reduced phase space in the nuclear medium as well as the compressed nuclear density. The energy available for the annihilation products was evaluated self-consistently, considering additional energy shift due to particle momenta in the anti-p-nucleus system. Next, we constructed the anti-p-nucleus optical potential using scattering amplitudes related to the latest version of the Paris anti-NN potential. We explored energy dependence of the potential and the implications for anti-p-nucleus quasi-bound states.
