Perturbation Theory,An exact solution of the Schrödinger equation exists only for a few idealized problems; normally it has to be solved using an approximation method. Perturbation theory is applied to those cases in which the real system can be described by a small change in an easily solvable, idealized system.

Spin,We have often mentioned the spin of the electron in our previous considerations. In this chapter we want to discuss the experimental evidence for the existence of spin. Furthermore, we shall develop its mathematical description.

A Nonrelativistic Wave Equation with Spin,In this chapter we introduce a new method of deducing — in a systematic, theoretical manner — the Pauli equation for the electron .. In contrast to earlier derivations, we do not refer to empirical facts, but develop the new theoretical concept of the ..

The Radiation Laws,h-Jeans radiation law acounted for experiments in the region of long-wave radiation; Wiien’s law for those in the region of short-wave radiation. By introducing a new constant ., Planck was successful in finding an interpolation between the two laws.

Mathematical Foundations of Quantum Mechanics I,by an operator function .] in a state . by . where . is the operator which is somehow related to .. In a first approach we are now going to deal with operators from a more general point of view. After this we shall determine a class of operators which is very important in quantum mechanics.

The Formal Framework of Quantum Mechanics, relations which will be considered here have already been discussed in the preceding chapters in a more “physical” way and most have been proved in detail. Some of the explanations and proofs are supplemented or demonstrated once again in a more compact manner in additional exercises.
