Mass renormalization deduced from the spectral weight and the width of the quasi-particle band around the chemical potential $\\mu$ is compared with that deduced from the electronic specific heat. The result implies that, near the MIT, band narrowing occurs strongly in the vicinity of $\\mu$. Spectral weight transfer occurs from the coherent to the incoherent parts upon antiferromagnetic ordering, which we associate with the partial gap ","authors_text":"A. Fujimori, A. Ino, T.
