الملخص EN

In this work, we present theoretical study for the effect of laser field on the localized state formation in the case of absorption and emission for atom adsorbed on solid surfaces system.

Anderson model is used as abases for the treatment by considering the derived occupation numbers in the presence of laser field, since the local density of states on the adatom in the case of absorption and emission.

In this treatment two controllable parameters are used, these are the frequency and strength of laser coupling.

We also introduce the effective density of states concept and extended model parameterization is presented.

The treatment parameters are all highlighted, such as the hopping strength and the laser parameters to investigate the scattering process features.

This treatment is applied to the system H / W (111) and according to our results, we conclude that there is obvious effect for the laser field (especially coupling strength) in determining the localized states energies and their occupation numbers.
