| 英文摘要 | the photoionization of seeded benzene beam by 25 ns laser pulse at wavelengths of 266, 355 and 1064 nm has been studied by the time-of-flight mass spectrometry. the observed mass spectra at 266 run and 355 nm at intensities of 10(10) similar to 10(11) w/cm(2) indicate a multiphoton ionization and dissociation (mpid) process, in which c+, c2hx+, c3hx+, c4hx+ and c6h6+ are main products. while at 1064 nm laser of similar intensities, the domain ion is c4+ which is produced from coulomb explosion. the longer wavelength facilities the energy absorption rate during inverse bremsstrahlung, which leads to the resulting wavelength dependence of the multicharged atomic ions. |
