Abstract

Utilizing the test systems αU, UBe₁₃, US and UTe, the unoccupied 5 f density of states is extracted from their Bremsstrahlung Isochromat Spectroscopy (BIS) based upon a jj picture of angular momentum coupling. Using a simple model and one set of parameters, it is found that it is possible to reconstruct the essence of the BIS results of all four test cases.
