| Abstract | ||
| In this work, extended theoretical study for the molecular chemisorption for diatomic molecule on metals surfaces is presented.Our treatment is based on Anderson model for the atomic chemisorption , since the molecule is considered as two atoms interacted between each other and with the surface. And by getting use of incorporating the surface temperature effect , analytic expressions are derived for the occupation numbers of the virtual atomic energy states. The direct and indirect interactions and also the image, and correlation effects are all taken into account . Our treatment is applied for the system H2/W, since the occupation numbers and all the related chemisorption functions are calculated as a functiona of the normal distance between the surface and molecule as well as the distance between the atoms . The results explain the well known physical general feathures for the system . | ||
