Abstract
An angle-resolved electron energy loss apparatus has been constructed for s tudying electron scattering by gaseous molecules. Generalized oscillator st rength distribution of H2O has been determined by the use of the Bethe sum rule and is presented as a form of Bethe surface, covering the momentum tra nsfer range from 0.52 to 3.36 a.u. and the energy loss range up to 400 eV. X-ray incoherent scattering factor or static structure factor S(K) has been subsequently derived and compared with those by theoretical calculations a s well as by inelastic X-ray scattering studies. S(K)s by the three differe nt methods show remarkable agreement. (C) 2000 Elsevier Science B.V. All ri ghts reserved.
