Abstract:	The changes in the positional parameter of neodymium in Nd_1.85Ce_0.15CuO₄ under high pressures differ from those observed in Nd₂CuO₄; in fact, practically no changes in the positional parameter in the doped oxide are observed. The different behavior of the positional parameter in these materials is explained by the compensation of the interlayer charge transfer by the interlayer repulsion occurring during doping or under the action of high pressures.
