Abstract
Atomic parity non-conserving (PNC) effects are produced by electronic weak interactions and lead to macroscopic mirror asymmetries. These PNC effects can be measured experimentally but in order to extract fundamental information about the weak force it is necessary to have accurate atomic calculations of the appropriate PNC El transition matrix elements. In this paper we give an over-view of relativistic calculations of PNC effects in atoms according to successive approximation schemes. From the combination of atomic PNC experiment and theory we derive an accurate value for sin2Өw. the fundamental electro-weak mixing angle. which is in excellent agreement with the current world average.
