  We propose iterative methods for obtaining solvation structures on a solid
plate which use force distributions measured by surface force apparatus (SFA)
and atomic force microscopy (AFM) as input data. Two model systems are
considered here. In the model system for SFA, the same two solid plates are
immersed in a solvent, and a probe tip and a solid plate are immersed in a
solvent in the model system for AFM. Advantages of the iterative methods are as
follows: The iterative method for SFA can obtain the solvation structure, for
example, in a Lennard-Jones liquid; The iterative method for AFM can obtain the
solvation structure without an input datum of solvation structure around the
probe tip.
