| 1. | Hot atoms are expected to play important roles in UV light.
|
| 2. | Elucidating the role of hot atoms on surfaces will lead to a deeper understanding of the mechanism of reactions.
|
| 3. | This high kinetic energy needs to be transferred somewhere else, because hot atoms tend to thermally ionize their electrons away.
|
| 4. | Such a hot atom does not fly into vacuum but is trapped on the surface, where it diffuses with high energy.
|
| 5. | In case 2, B gains a high translational energy from the adsorption energy of A, and hot atom B is generated.
