| 英文摘要 | the electron energies were measured to investigate the influences of laser intensity and wavelength on the ion charge state distribution of c(q+) (q = 2-4) when benzene clusters were irradiated by 10(9)-10(11) w/cm(2) nanosecond laser pulses. the results show that the ratios of c(q+)/c((q) (1)+) strongly depend on laser wavelength but slightly on laser intensity. the mean electron energy up to 100 ev was measured, which was qualitatively consisted with the 'multiphoton ionization ignition-inverse bremsstrahlung heating-electron impact ionization' three-stage model. the screening effects inside clusters can significantly decrease the ionization potentials of c(q+) and facilitate the formation of multiply charged ions especially at low laser intensity.
