英文摘要The photoionization of acetonitrile seeded in helium is studied by time-of-flight mass spectrometry using a 25 ns, 1064 mn Nd:YAG laser with intensity near 10(11) W center dot cm(-2). Multiply charged ions of Nq+(q=1 similar to 5)f1J Cq+ (q =1 similar to 4)(sic)C(q+)with hundreds of eV have been observed under laser beam irradiation with the densest portion of the pulsed molecular beam. An electron re-scattering and re-colliding ionization model is proposed to explain the generation of those multiply charged clusters under such low laser intensity.
