High Resolution Scattering of He Atoms and D₂ Molecules from the LiF(001) Crystal Surface

Abstract

In the present dissertation a flexible, high-resolution molecular beam apparatus is described which allows surface scattering experiments over a wide range of final angles for fixed incident angles of 0 to 90 degrees. These features have been utilized in this work for investigation of the free-jet expansion of D 2 beams and the scattering of He and D 2 beams from LiF(001) and Si(111):H(1×1) surfaces.• Finally, in Chapter 8, the attained results and conclusions are summarized and the future work under the fiat of obtained knowledge from this work is pointed.
