Time-of-flight spectra of H atoms from photodissociation of a polycrystalline ice film at 157 and (open circles). The solid lines are fits to the data derived assuming three Maxwell-Boltzmann distributions at , with for , for , and for (upper trace, shown by the dashed lines), and one distribution at , with (, lower trace). Relative populations are listed in Table I.
Time-of-flight spectra of H atoms from photodissociation of amorphous solid water films at 157 and . The translational temperatures of the various contributory components are the same as in Fig. 1.
Schematic diagram of H atom formation processes from an amorphous ice film. , , , and represent the Maxwell-Boltzmann components listed in Table I.
