1 INTRODUCTION

This chapter is a continuation of the material presented in a previous Summer School (Ref. 1). Some of the basic formalism needed in discussions of parity-conserving and parity-violating electron scattering is repeated here to make the notes reasonably self-consistent, although in several instances the main results are merely summarized and the reader is encouraged to find the details in Ref. 1.

This chapter is organized in the following way. In Section 2 the nature of the leptonic tensor is reviewed and extensions to include both incident and scattered electron polarizations incorporated. The general problem was treated in Ref. 2 here the author has chosen to present some new results for the leptonic polarization transfer process. In Section 3 the nature of the hadronic tensor and the electromagnetic hadronic (nuclear) response functions are again discussed. Recent work on the inclusive process A(e, e ?) is reported in the first part of the section, after repeating the familiar arguments leading to the unpolarized inclusive electron scattering cross section. The subject of inclusive scattering from polarized targets, on the other hand, is not discussed here and the reader is referred to Refs. 1 and 2 for treatments of those concepts. Following this, again drawing on Ref. 1 the basic form of the multiparticle coincidence reaction for electron scattering with no hadronic polarizations is recalled and...
