Abstract EN

To studying the effect of the Adatom-Adatom interaction through out the scattering of atom from surface, Anderson Hamiltonian is used which incorporates the interaction of the scattering atom with the adatom and the interaction of the adatom with the surface atoms.

Since the atom is scattered from the adatom and the charge transfer happens through out resonance and quasi-resonance charge transfer.

The Hamiltonian incorporates also the electron-phonon coupling interaction.The system of equations for scattered atom-adatom / surface is treated using the wide band approximation.

The systems of equations are solved numerically using six-order Runge-Kutta method with the accuracy is checked at each time.

The treatment is applied to real system, that is Li-K/W, This search include effect intraction J on the occupation number of adatom and number of phonons and This search include effect of temperature of surface on the occupation number of adatom and number of phonons resultant from scattering.
