Extraction of baryonia from the lightest anti-protonic atoms
arXiv:2007.01775 · doi:10.1103/PhysRevC.102.034006
Abstract
Anti-protonic hydrogen and helium atoms are analyzed. Level shifts and width are expressed in terms of -nucleon sub-threshold scattering lengths and volumes. Experimental data are compared to results obtained from the 2009 version of the Paris interaction potential. Comparison with 1999 version is also made. Effects of quasi-bound states are discussed. Atomic 2P hyperfine structure is calculated for antiprotonic deuterium and the significance of new measurements is indicated.
