Abstract

Many different types of electron spectroscopies are nowadays widely used to probe the electronic states of solids. Quite often the results are directly compared to theoretical calculations or introduced in models supposed to explain other experimental results. The validity of these approaches is seldom discussed since the spectroscopic results are implicitly assumed to reflect simply a rigid single-particle density of states (DOS). In fact this way to proceed is in most cases an approximation which may become very poor or even break down when the correlation of the states involved in the considered process increases. These problems are very closely related to the formation of moments in solids, which is only possible in highly correlated systems where the exchange energy can become strong enough to favour a particular ground state.
