【 摘 要 】

We present density functional theory calculations within the generalized gradient approximation of U2RhC2and U2PtC2. We find the calculated density of states are significantly less than that measured by specific heat indicating the need for electronic correlations. The mass enhancement found for U2PtC2is m∗/mband≈ 4.
