Extraction of baryonia from the lightest antiprotonic atoms

Résumé

Antiprotonic hydrogen and helium atoms are analyzed. Level shifts and width are expressed in terms of p¯-nucleon subthreshold scattering lengths and volumes. Experimental data are compared to results obtained from the 2009 version of the Paris NN¯ interaction potential. Comparison with the 1999 version is also made. Effects of NN¯ quasibound states are discussed. Atomic 2P hyperfine structure is calculated for antiprotonic deuterium and the significance of new measurements is indicated.
