New parametrizations for the electric and the magnetic form factors of a proton and neutron are presented. The proton form factors describe well the recent measurements by the BABAR Collaboration and earlier ones of the ratio of the form factors in a spacelike region. The neutron form factors are consistent with earlier measurements of neutron pair production and ratio of the form factors in the spacelike region. These form factors are implemented into the generator phokhara, which simulates the reactions e+e^\ensuremath-\ensuremath→pp\ensuremathγ and e+e^\ensuremath-\ensuremath→nn\ensuremathγ. The influence of final state radiation is investigated.
