Abstract
Generalized oscillator strengths (GOS) as functions of momentum change are reported for four peaks in the electron impact spectrum of water vapor. Differential generalized oscillator strengths are also reported at seven points in the continuum. Extrapolated (to ΔP=0) oscillator strengths are given at even finer intervals. Most of the experiments were done at about 500 eV kinetic energy, but two transitions were studied at 400 eV kinetic energy to test the Born approximation.
