    "abstract": "In this paper I review a number of recent results in the field of exotic\natoms. Recent experiments or ongoing experiments with muonic, pionic and\nantiprotonic hydrogen, as well as recent measurement of the pion mass are\ndescribed. These experiments provide information about nucleon-pion or\nnucleon-antinucleon interaction as well as information on the proton structure\n(charge or magnetic moment distribution).",
