Atomic oxygen is photogenerated in solid D2 by 193 nm irradiation of samples initially doped
with molecular oxygen. The atoms are detected by laser-induced fluorescence at the
O(1
S1
D) transition, which occurs at 559 nm, with a fluorescence lifetime of 230 s. The
absorption leading to this emission is indirect, attributed to O2(X):O(3
P) pairs. Complementary
studies are carried in solid D2 co-doped with Xe and O2, in which, in addition to ionic
XeO centers, the atomic O(1
S1
D) transition with a radiative lifetime of 50 s is observed.
The photogeneration of the atomic centers and the stability of the atomic and molecular
