Plans for Measurement of Parity Nonconservation in Elastic Scattering of Polarized Electrons by Nuclei at the Bates Linear Accelerator Center

We are planning to measure the parity-violating asymmetry A=(σ⁺−σ^#x2212;)/(σ⁺+σ^#x2212;) for the differential elastic scattering of positive (+) and negative (#x2212;) helicity electrons from ¹²C nuclei. This asym...
