We present a new study of double production in the e
+
e
– continuum. We report a study of many double charmonium final states in e
+
e
– annihilation. The 
cross-section is measured with reduced model dependence. The cross-section of the coherent pair production in the e
+
e
– continuum is measured for the first time.
