  Comments:
  Atomic Orbital close coupling calculations for He2+ colliding with Lithium
  atoms in various initial states (2s,3s,2p,3p,3d) have been performed using a
  single set of basis states. The expansion includes travelling atomic
  orbitals on the He2+ centre (n-shells 1 - 6) and LiI states up to Li(5g).
  The latter states have been obtained by diagonalisation of the atomic
  Hamiltonian with a model potential. In addition to these bound states
  pseudo-states are included which improve the convergence behaviour and
  represent ionisation. Altogether, the expansion consists of 87 states on
  the He centre and 80 on Li.  From these calculations partial
  cross sections for charge exchange into HeII(nl) (n=1-6) have been deduced
  in an energy range of 1.5 - 20 keV/amu. The accuracy is believed to be 5-10%
  for cross sections > 10**-15 cm**2 and 30-40% for those < 10**-16 cm**2.
