摘要：

Using photoemission spectroscopy (PES), we have investigated the electronic structure of UNiSn. The U 5f spectrum of UNiSn shows a broad peak centered at approximate to0.3 eV BE, suggesting that the hybridization matrix element between the f-electron orbitals and the very low Ni 3d DOS at E-F is important. The high-resolution PES spectrum of UNiSn is described well by a V-shaped metallic DOS near E-F, implying the reduced 5f DOS at EF. (C) 2002 Elsevier Science B.V. All rights reserved.
