Experimental study of the pd(dp) → 3He ππ reactions close to threshold

NUCLEAR REACTIONS 1H(d, 3Heπ+π-), 2H(p, 3Heπ+π-), at Q<100 MeV; measured 3He using high-resolution spectrograph Big Kar, and charged pion spectra using MOMO detector at COSY accelerator facility in Julich, ΔE-E and time-of-flight (TOF) measurements for particle identification, differential σ as function of kinetic energy of pions; deduced estimate of π0π0 production. Comparison with previous experimental data, and with predictions of two-step model.
