Measurements of the Electric and Magnetic Form Factors of the Neutron for Timelike Momentum Transfer
Measurements of the Electric and Magnetic Form Factors of the Neutron for Timelike Momentum Transfer
We present the first measurements of the electric and magnetic form factors of the neutron in the timelike (positive q^{2}) region as function of four-momentum transfer. We explored the differential cross sections of the reaction e^{+}e^{-}→n[over ¯]n with data collected with the BESIII detector at the BEPCII accelerator, corresponding to …
