The reaction γ+d → π++π−+p + n has been measured in a kinematically complete way at incident photon energies from 570 to 850 MeV in steps of 40 MeV. From detailed comparison of measured data with results of event simulations, it is concluded that three different mechanisms, the quasi-free, double-delta and phase space productions, contribute to the reaction. Each of the cross sections corresponding to these mechanisms is determined separately.

The Total cross-section for the He-4 (gamma, n p p) n reaction in the Delta resonance region

This is the first measurement of the total cross section σ( 4 He (γ npp)n) in the range of 135–455 MeV. The σ, which cannot be reproduced by any model, has similar E γ dependence to γ T (γ 4 He → all channels). The averaged ratio σ( 4 He(γ, npp)n)/ σ T (γ 4 He → all channels) = (2.3 ± 0.3)% is compared with a cascade-model calculation in which quasi-free pion production followed by pion reabsorption is assumed.
