Chapter 11

Symmetry and Conservation

Iraj R. Afnan

Abstract

With symmetry playing a central role in quantum mechanics, in this chapter we commence with the simplest of symmetries of translation in space and time. Here we consider the group structure of the symmetry operators. This is followed by a rotational symmetry that plays a central role in atomic and nuclear physics and is a major component of this chapter. Finally we examine time and space reversion and isospin that are central to the study of nuclear and particle physics.
