Phys. Rev. Lett. 82, 3236–3239 (1999)Strong Alignment Effect in Quasiresonant Charge Transfer between Laser-Excited Sodium Atoms and C60Received 2 October 1998; published in the issue dated 19 April 1999 We observe a strong alignment effect (〈ρσσ〉 = 0.8±0.2) in quasiresonant charge transfer collisions between Na(3p) and C60 at thermal energies. This implies that practically only excited sodium atoms with their electronic charge cloud asymptotically aligned along the relative velocity vector lead to charge transfer. This is interpreted as being due to a combination of “orbital locking” and the strong π-like character of the fullerene lowest unoccupied molecular orbital. © 1999 The American Physical Society URL:
