Abstract

This Letter reports the first measurements of the angular distribution of Auger electrons emitted from the decay of the (1s2s2p²)³D O^4+** doubly excited state formed predominantly through resonant transfer and excitation (RTE) in collisions of 13-MeV O⁵⁺ projectiles with He. The (1s2s2p²)³D angular distribution is strongly peaked along the beam direction, in agreement with recent calculations of the RTE angle-dependent impulse approximation. Furthermore, interference effects between the RTE and the elastic target direct-ionization channels are observed.
