摘要：

The electronic specific heat coefficients gamma for single crystals of a perovskite-type 3d(1) vanadate system, Ca1-xSrxVO3, are reported. Wilson's ratio Rw has been determined by comparing the data to the Pauli-paramagnetic susceptibility; the value Rw similar or equal to 2 indicates a strong electron correlation in this system. Nevertheless, the effective masses are not so large as expected from the critical-mass-enhancement picture near the Mott transition.
