Description

The role of pions in nuclei has been studied in pionic fusion, a highly coherent process in which two nuclei fuse to a united nucleus. The available center-of-mass energy is emitted in the pion channel. This production mechanism is sensitive to the pion-nucleon interaction and the structure of the fused nuclei, in particular to their cluster components. The experiment exploits the two-photon decay of neutral pions and provides the exclusive cross sections for the 4He(3He,π0)7Be and 6Li(4He,π0)10B reactions at energies just above the coherent production threshold. The pion angular distributions and their dependence on the fused system mass reflect the importance of the cluster sub-structure of nuclei and the pion interaction in nuclei.
