AbstractThe collision-induced reaction of Lif with neutral C-60 vapor was investigated in the energy range of 10-100 eV using laser desorption time-of-flight mass spectrometry (TOFMS). From the positively charged TOF mass spectra, the maximum intensity of [Li@C-60](+) was determined, which was about 60% of that for the C-60(+). In addition, [Lil@C-60](+) complex was also observable. The negatively charged lithium endohedral fullerene ions of both fragment products (C-5s) and adductive products were observed in the negatively charged TOF mass spectra for collision energies in the range of 30-50 eV. In addition, it was found that up to three lithium atoms can be trapped into the fullerene cages and the intensity of [LimC60+2n](-) (m = 1,2 and 3, n = 0, 1,2, 3,4) in the mass spectra decreases with the increase of m and n. Li+ inserts into the C60 cage via a "slip-through" mechanism was proposed. (C) 1998 Elsevier Science B.V.
