| 英文摘要 | the photoionization of methyl iodide beam seeded in argon and helium is studied by time-of-flight mass spectrometry using a 25 ns, 532 nm nd-yag laser with intensities in the range of 2 x 10(10)-2 x 10(11) w/cm(2). multiply charged ions of iq+ (q = 2-3) and c2+ with tens of ev kinetic energies have been observed when laser interacts with the middle part of the pulsed molecular beam, whose peak profiles are independent on the laser polarization directions. strong evidences show that these ions are coming from the coulomb explosion of multiply charged ch3i clusters, and laser induced inverse bremsstrahlung absorption of caged electrons plays a key role in the formation of multiply charged ions.
