โฆ Synopsis
The spectra of the radiofluorescence RF, afterglow AG and the Ulermotuminesccnce TL of H20 and D20 ice are reported. The RI: spectrum of l&O exhibits !WO bands, whereas for 1120 only one of these is seen. The spectrum of TL is difierent from that of RF and AG. It is argued that if any of these spectra arc due to de-excitation of the triplet state of water it is that of tic TL. Tllis spectrum is peaked at 335 + 3 nm and has a width of 46 nm.

The results are especially encouraging in the light of Konowalov's calculation [8]. He found that Hulth&n functions (integral transforms of 1s functions), which are somewhat better than k,(q) in the Z-electron+atomic case, reduce to scaled 1s functions in H2, except for larger R values.
