TDHF STUDY OF THE HE-8 GROUND-STATE ENERGY( COLLISION ON ATOMIC HE TARGETS AT THE BE)

Experimentally the Be-8 ground state resonance has been studied in He collisions on atomic He atoms. The nuclear resonance manifests itself by satellite resonance lines corresponding to different electron conf igurations of the Be ion. Experimentally a large probability for the e mission of one electron has been deduced. We study the atomic He+ + He collision within a model in which the evolution of the electron wavef unction is treated dynamically in the TDHF scheme, and the motion of t he nuclei is treated classically. In agreement with experiment we find a large probability for one electron to be emitted into the continuum during the lifetime of the Be-8 ground state resonance.
