Abstract
One of the most important problems of quantum mechanics is to calculate the probabilities of transitions from one quantum state to another. This problem may be formulated as follows. Suppose that at time t = 0 we have a pure ensemble of systems which is such that some mechanical quantity L has a definite value L = L n . Such an ensemble will be described by a wave function Ψn(x) which is an eigenfunction of the operator L belonging to the eigenvalue1 L = L n . Systems belonging to such an ensemble are said to be in the quantum state n.
