We have investigated the dependence of the oxygen isotope effect on the hole density in the high-T~ cuprates Bi2Sr2CaCu2Os and YBa:Cu~Os. The hole density n was varied by partial replacement of Ca by Y (hole acceptor) in BizSr2CaCu2Os, and by partial replacement of Y by Ca (hole donor) in YBa2Cu4Os.
