Abstract
The fine and hyperfine structure of light antiprotonic atoms in states of angular momentuml>0 is calculated. The fine (=l-dependent) structure is dominated by vacuum polarization up to a certainl-value (l=4 for¯pp), and by relativistic effects for largerl. Meson exchange is important only in the hyperfine (=spindependent) structure of theP-states. For¯pp and¯p 3He, the hadronic part of the hyperfine structure is dominated byπ 0-exchange.
