Abstract
The electron density distribution of the cells of Y3+Ba2Cu3O7 and Pr4Ba2Cu3O7 is calculated and mapped. It is shown that the substitution o f Y3+ ion by Pr4+ ion deforms the electron density distribution ill th e vicinity of the CuO2 planes. It is supposed, that supercurrent flows in two-dimensional layers of the lowest electron density.
