The extremely sophisticated techniques developped in atomic physics especially in combination with laser-optics allows the measurement of very small effects. Such experiments are therefore able to detect e. g. the parity violating interaction due to neutral currents1′3. Before we discuss the type of effects one observes and how one calculates the theoretical predictions let us make some general remarks about the role of the discrete symmetries for the wave-function of a bound Dirac-particle (for problems with spherical symmetry).
