Abstract

The first exclusive measurements at CELSIUS-WASA for the double-pionic fusion to d or He-3 reveal the ABC effect - a low-mass enhancement in the pi pi invariant mass spectrum - to be a sigma channel phenomenon associated with the formation of a Delta Delta system and combined with a resonance-like behavior in the total cross section. This quasibound system with a mass below the Delta Delta threshold obviously survives also in nuclei as a resonance configuration producing the ABC effect there. (c) 2007 Elsevier B.V.
