The atomic collisional energy transfer from a gas to a one dimensional lattice is investigated by the use of classical mechanics throughout. A general equation of motion is derived by arbitrary interactions and surface impurity. In two special cases the energy transfer is solved exactly under the assumption in which the repulsive force acts upon the gas aton. The efficiency of energy transfer from the calculation is much higher than that which is predicted by Lennard-Jones's one phonon approximation. The detailed calculation is performed more generally than the result which J. W. Zwanzig has obtained. In the limiting use of repulsive force (hard sphere potential), gas atom which has lighter mass than that of surface impurity collides only once and heavier gas atom two or note tines with one dimensional lattice. And as the masses of gas and surface impurity decrease, the energy transfer in collision increases monotonously. It is shown that the motion of semi-infinite lattice with a surface impurity can be solved in terms of the notion of the corresponding infinite lattice with an impurity at its centre.
