| Popis: | The impact of low energy (10–30 keV) H + and He + ions on polycrystalline aluminum gives rise to broad band optical emission; this extends from 3000 to 6500 A and peaks in intensity near 5100 A. The integrated intensity in this band represents approximately 0.02 photons emitted for each ion incident. All observations are consistent with the source of the emission being localized in the target surface. We suggest that this emission is due to a recombination mechanism involving electrons localized (in reciprocal space) at a minimum in an excited band at the critical point W. We calculate the spectral distribution expected from this direct-transition, electron-hole recombination model and show that the result is consistent with the observed spectrum. |
