Abstract.

A measurement of the parity-violating asymmetry in elastic scattering of polarized electrons on protons is currently running within the A4 Collaboration at the MAMI facility in Mainz. The aim is to reveal the contribution of strange quarks to the form factors of the nucleon at a Q 2 = 0.23 GeV2. The expected asymmetry without strangeness is around 5.4 x 10-6. After 600 hours of asymmetry data taking, an accuracy of 1 x 10-6 has been achieved.
