Abstract
We applied the heavy atom method to obtain the light atom positions of multi-solution type in the case of heavy atoms possessing a pseudo-symmetry whiCh is higher than that of the who'e structure. We introduced a model of pseudo-structure, derived an expression of diffraction structure factor FM(H) for a pseudo-structure and gave an estimate of correction term |EP(H)|.When we apply the heavy atom method of multi-solution type to a known structure, a perfect pseudo-structure pattern in obtained.
