    Abstract

    Dissociative multiple ionization processes of N2 were investigated by irradiating N2 with an intense extreme ultraviolet (XUV) light at 50.3 nm generated by a compact self amplified spontaneous emission free electron laser light source. From the analysis of the momentum distribution of N+ ejected through the Coulomb explosion of N2 and by the single-shot correlation between the yields of N2+ and N+, it was confirmed that double ionization of N2 occurred by the two-photon absorption of the XUV light.
