Electron bubbles, small-polaron holes, and charge-induced effects in solid deuterium

The charge-induced absorption spectrum in the fundamental band of solid D2 under proton-beam irradiation has been measured. Under higher spectral resolution than for previous work, we examine the spectra for both normal and ortho-enriched samples. Timing experiments are presented in which the growth and decay of these spectral features are monitored following onset and termination of beam irradiation, and both spectra and timing as a function …
