摘要
The first measurement of the Compton profile of polycrystalline yttrium is reported. The data, obtained using 59.54 keV gamma-rays are compared with available APW band structure calculations, with and without electron correlation effects. Theoretical computations have also been carried out using the renormalized-free-atom (RFA) model for various 4d-5s configurations. It is found that the present experimental data are in better agreement with the APW band structure calculation without an electron correlation correction. Among the RFA calculations, the best agreement between theory and experiment is found if the outer electron configuration is chosen as 4d(1)5s(2).
