The Radiation Laws,yleigh-Jeans radiation law acounted for experiments in the region of long-wave radiation; Wien’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 Schrödinger Equation,subject to certain boundary conditions. At the very beginning of the development of quantum mechanics, one was faced with the problem of finding a differential equation describing discrete states of an atom. It was not possible to deduce exactly such an equation from old and well-known physical prin

Identical Particles,that have the same mass, charge, spin etc. and behave in the same manner under equal physical conditions. Therefore, in contrast with macroscopic objects, it is not possible to distinguish between particles like electrons (protons, pions, . particles) on the basis of their characteristics or their t

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.
