Description
We report the first experimental observation of the pionic fusion of two heavy ions. The 12C(12C,24Mg)π0 and 12C(12C,24Na)π+ cross sections have been measured to be 208±38 and 182±84 pb, respectively, at Ecm=137 MeV. This cross section for heavy-ion pion production, at an energy just 6 MeV above the absolute energy-conservation limit, constrains possible production mechanisms to incorporate the kinetic energy of the entire projectile-target system as well as the binding energy gained in fusion
