Convergent perturbative solution to the attractive corrugated hard wall model of atom--surface scattering
The attractive corrugated wall model of atom--surface scattering is solved by an expansion method. The approach is similar to a Born expansion; however, projection operators must be introduced in order to obtain a convergent series near resonances. Diffraction intensities are calculated for He--LiF(001) and He--NaF(001) scattering. Good agreement with experimental intensities is obtained when the series is taken to convergence. In some cases (He--NaF) this requires calculation to as high as 12th order in the expansion parameter. At this order as many as 169 channels are included in the calculation. Preliminary estimates for the values for v/sub 01/ and v/sub 11/ for the He--NaF system have been found by comparison of theoretical and experimental intensities.
