Abstract
The change in the Cu-64 electron-capture constant for the compounds Cu 2O, YBa2Cu3O7 YBa2Cu3O6, Nd2CuO4, Nd1.8Ce0.2CuO4, La2CuO4, La1.7Sr0.3C uO4, Tl2Ba2CaCu2O8, and Bi2Sr2CaCu2O8 has been measured. It is conclud ed that the copper in YBa2Cu3O7, Nd2CuO4, La2CuO4, La1.7Sr0.3CuO4,Tl2B a2CaCu2O8, and Bi2Sr2CaCu2O8 is exclusively divalent, whereas in Cu2O, YBa2Cu3O6, and Nd1.8Ce0.2CuO4 univalent copper is present.
