Generalized oscillator strengths are given for the l lA 1B1
transition-in H20 at electron kinetic energies of incidence of 300, 400, 500
and 600 eV. The data have been used to calculate the excitation energy
of the 3B1 state (lowest) of H20. The result is 7.0 .1 eV where the
uncertainty is an estimate not an upper bound. This confirms our previous
conclusion that the 4.5 eV excitation, observed by several investigators,
cannot be due to vertical excitation to the lowest 3B1 state. The 4.5 eV
excitation is not yet identified. Generalized oscillator strength deter-
minations on CO2 are also reported together with preliminary results on
a survey of N2 spectra, at several kinetic energies and angles, in the
vicinity of 11.87 eV, the excitation energy for the transition X 1E + E 3
Cross section determinations on 1S -+ 23S transition in helium at high
kinetic energy (supported by AFOSR) are also briefly described since the
results are of considerable interest in the present research.
Here’s what’s next.
