Abstract

We carried out time-of-flight mass spectrometry for neon clusters that were exposed to intense free electron laser pulses with the wavelength of 62 nm, which induce optical transition from the ground state (2s² 2p ⁶) to an excited state (2s² 2p⁵ nl ) in the Ne atoms. In contrast to Ne⁺ ions produced by two-photon absorption from isolated Ne atoms, the Ne⁺ ion yield from Ne clusters shows a linear dependence on the laser intensity (I). We discuss the ionization mechanisms which give the linear behaviour with respect to I and expected features in the electron emission spectrum.
