Single atom inage intensities are calculated for bright-field and various dark-field modes, including the ideal beam stop, a wire beam stop, tilted illumination and a displaced aperture. Comparisons of scattering amplitudes and elastic scattering cross-sections are made with different object potentials and scattering formulations. The image contrast for one mercury atom (Z equals 80) on a column of carbon atoms (Z equals 6) as the substrate is also discussed for both the bright-field and the various dark-field situations.
计算了明场和各种暗场模式下的单原子图像强度，包括理想束流阻挡、线束流阻挡、倾斜照明和位移孔径。对不同物体势和散射公式下的散射振幅和弹性散射截面进行了比较。还讨论了以碳原子柱（Z等于6）为衬底时一个汞原子（Z等于80）在明场和各种暗场情况下的图像对比度。
