    "abstract": "Recently observed rare heavy ion fusion processes, where the entire available\nenergy is carried away by a single pion, is an example of extreme collectivity\nin nuclear reactions. We calculate the cross section in the approximation of\nsudden overlap, modeling the initial and final nuclei by moving harmonic\noscillator potentials. This allows for a fully quantum-mechanical treatment,\nexact conservation of linear and angular momenta and fulfillment of the Pauli\nprinciple. The results are in satisfactory agreement with data. Mass number\ndependence and general trends of the process are discussed.",
