The cross sections for the emission of Lyman-alpha fluorescence in the photoexcitation of H(2)O have been measured as a function of the incident photon energy in the 14-60 eV range, i.e. the outer-and inner-valence ranges. Four superexcited states have been found, two of which are doubly excited states, one is a singly excited state and one a state including electron configurations of both single and double excitations. The gross feature of the superexcited states of H(2)O resulting in the formation of excited hydrogen atoms has been obtained by combining the present results and the cross section curves of the Balmer fluorescences (Kato et al 2004 J. Phys. B: At. Mol. Opt. Phys. 37 3127). The breakdown of the independent electron model has been indicated in the inner-valence range of H(2)O, and the degree of breakdown has been compared among CH(4), NH(3) and H(2)O ten-electron molecules.
