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