Abstract
It is shown that electron correlation among Cu d-electrons explains the photoemission data of CuGeO3 and is responsible for the insulating behaviour and of the observed complex satellite structures. The analysis and interpretation of the experiments require the use of a multi-band Hamiltonian which explicitly includes both on site electron correlation and a detailed description of the single-particle band states.
