摘要

Abstract The strong-interaction effects in antiprotonic 16O, 17O, and 18O atoms were measured at the CERN antiproton facility, LEAR. The shifts ϵ and the widths Γ of the 3d level were determined to be −112±20 eV ( 16 O ) , −140±46 eV ( 17 O ) , −195±20 eV ( 18 O ) , and 495±45 eV ( 16 O ) , 540±150 ( 17 O ) , 640±40 eV ( 18 O ) , respectively.
