The associated production of a and a final hard photon in high energy electron-positron colliders is studied. It is shown that the hard-photon spectrum contains useful information on the properties. This suggests that, if a new neutral gauge boson exists for 
, it will not be necessary to make a new energy run at the mass in order to get most of its properties.
