With a partial-wave interpolation method we calculate the electron bremsstrahlung energy spectra from neutral atoms with atomic number Z = 13 and 92 for incident electrons of kinetic energy T/sub 1/ = 5 and 10 MeV. This is an attempt to bridge the gap between the results we have previously obtained for T/sub 1/ < or = 2 MeV and the results which can be predicted in the high-energy limit. We conclude that for light elements Born approximation modified by the Elwert factor and a form factor remains accurate, while for heavier elements the Davies, Bethe, Maximon, Olson approach is of comparable (5--10) % accuracy at these energies and continues to improve with increasing energy.
