| dc.description | A series of successively more accurate wavefunctions (of the natural orbital form) for the helium-atom ground state (the best yielding 98.6% of the correlation energy) is used to analyse the 1200 eV non-coplanar symmetric (e, 2e) data for helium with the plane-wave impulse approximation. Particular attention is focused upon the determination of the ratio for populating the n=2 (2s and 2p) and 1s ions states. It is seen that the cross section ratio (at low recoil momentum) converges satisfactorily as additional target natural orbitals are utilised for the calculation of the overlap function. The convergence of the cross section ratio at high azimuthal angles is seen to be much slower. |
