Pressure dependence of the exchange integral J in Nd3CuO,j was investig?tted by luigh-pressttretwo-tnagnon Raunan scattering. TI?e strpercondtrcting transition temperatures T0ita electron-doped high Tc) stmperconductors are knoxvn to be aluaaost indejcenderat of' pressture in contrast witluhole-doped ones. The obtained c1J 7dP ::: 12.4 Clll ' /GPa is, hoxvever, nearly the satne as tlnosein the insulating phases of hole-doped high T0strpercondtnctors. Tlae presstrre deperadence of tluehopping integral t..z is umuch larger tltan tlaose of hole-doped ones, becatrse the pressure coefficientof the clxar"e-transfer gap energy laas an opposite sign froraa that of hole-dopable structtrre,
