Emission, Absorption and Scattering of Light by Atomic Systems,cited state, or returns from an excited state to a lower one, under the action of incident light. In the former case the energy of the atom increases by an amount . − ., where . is the energy of the initial state and . that of the excited state, and in the latter case it decreases by this amount. Let us first consider the former process.

Foundations of Quantum Theory, between the corpuscular and wave theories of the nature of light the wave theory had finally triumphed in the form due to Maxwell. The experiments of Hertz with electromagnetic waves, the proof by Lebedev of the existence of radiation pressure, and other facts revealed by the experimenter’s skill s

Foundations of Quantum Mechanics,. Attempts were made at first to regard the particles themselves as consisting of waves and distributed in some region of space. The intensity of the de Broglie wave was regarded, on this view, as a quantity representing the density of the medium of which the particle was formed. This conception of

Change of State with Time,nstant . = 0. By means of this wave function we may calculate the probability of different results of measuring various mechanical quantities at time . = 0 for the ensemble of particles in the state ψ(., 0). In this sense we say that the wave function describes the state of a particle at time . = 0.

Theory of the Motion of Microparticles in a Field of Potential Forces,lly speaking, if the forces are independent of time, the basic problem of atomic mechanics is that of finding the stationary states of the system. For in this case, according to (30.8), an arbitrary state ψ(.) can be represented as a superposition of stationary states with constant amplitudes .: . w
