Physics Program in Hall A at CEBAF

We present here the physics program planned for Hall A at CEBAF. It encompasses exclusive as well as inclusive electromagnetic measurements requiring both high precision and accuracy.The program includes measurements of the elementary form factors of the nucleon, systematic studies of the few nucleon systems (d, 3,4He), high momentum structure of nuclei, their structure at high Q^2 to look for hadronization and quark effects, spin response of nuclei via (vector-e, e'vector-p) reactions and the study of nuclear pion fields
