Özet
In this study, we carried out an analysis of the oxygen isotope exponent in optimally doped Bi2Sr2Ca (n-1) Cu (n) O2n+4 + delta ( n = 1,2,3). The expression in the strong electron-phonon coupling approach for the isotope exponent taking into account numbers of CuO2 layers in the unit cell was obtained. It is shown that increasing numbers of CuO2 layers lead to the decreasing of the isotope exponent, which is in agreement with available experimental data.
