摘要：

A dramatic temperature-dependent enhancement of U 5f spectral weight at E-F is observed in angle-resolved photoemission measurements of URu2Si2 at the center of an X-point hole-pocket. Comparison of this temperature-dependent behavior for excitation both at and below the U 5d --> 5f resonant threshold is presented. (C) 2002 Elsevier Science B.V. All rights reserved.
