摘要：

The normal-state electrical resistivity p of the superconductor Rb3C60 has been measured as a function of temperature and hydrostatic pressure. Under conditions of constant sample volume we find a linear temperature dependence, rho approximately T, in sharp contrast to rho approximately T2 observed under conditions of constant sample pressure. The pressure dependence of rho at fixed temperature is exponential, with a reduction in rho by more than 50% for 8 kbar at room temperature. Implications for the normal-state scattering mechanism are discussed.
