英文摘要the formation mechanism for multiply charged ions ( c(q+) and o(q+) ( q = 2-4)) were investigated using a dual polarity time-of-flight mass spectrometer when diethyl ether clusters interacted with nanosecond laser pulse. the signal intensity of multiply charged ions and electron energy was measured experimentally. it was shown that the intensity of multiply charged ions increased about 50 times when laser intensity increased from 7.6 x 10(9) to 7.0 x 10(10) w/cm(2), then saturated as laser intensity increased further. it is interesting that the evolution of the mean value of electron energy was same to that of multiply charged ions. the theoretical calculation showed the ionization potential of atomic ions could be significantly decreased due to the effect of coulomb screening especially at low laser intensity. it indicated that the electron ionization combined with coulomb screening effect could explain the production of multiply charged ions in nanosecond laser field. crown copyright (c) 2010 published by elsevier b. v. all rights reserved.
