Abstract
Fully relativistic self-consistent LDA band-structure calculations for CeSn3 are reported using the LMTO method. Fermi surface areas are in agreement with experimental but band masses, density of states and electronic pressure are in wide disagreement. A one-parameter renormalisation prescription based on the large-N limit of the infinite-U Anderson model is introduced and the band structure recalculated. The 4f band then splits into distinct j=5/2 and j=7/2 bands. Using the renormalised band structure and band masses, density of state and electronic pressure are found to be in agreement with the experimental data.Keywords
