"Form factor measurements at MAMI"


Tuesday 21st March, 14:00h, F-201


    An overview of the form factor programme of the A1 Collaboration at
    MAMI is given. Results on the electromagnetic form factors of the
    proton measured with elastic electron scattering at four-momentum
    transfers Q^2 between 0.003 and 2 (GeV/c)^2 are reported, which
    allow extraction of the electric and magnetic radii of the proton.
    Data for scattering on the deuteron have also been taken and their
    analysis is ongoing.

    A novel technique to measure the electric form factor of the proton
    at very low Q^2 using initial state radiation is presented and
    results from a pilot experiment are shown.

    The design of a neutron recoil polarimeter for measurement of the
    electric form factor in a future double-polarisation experiment is
    presented.
