Abstract

The formation of hydrogen atoms from amorphous ice due to 193 nm photodissociation at 90-140 k is investigated. The time of flight spectra of the photofragment hydrogen atoms is also analyzed. It is observed that the spectra is made up of both a fast and a slow component that are characterized by average translational energies. The results show that the hydrogen molecules are formed due to the photodissociation of the ice surface that is attached by water molecules with the hydrogen bonds.
