Abstract: | We report on a high-statistics measurement of the most basic double-pionic fusion reaction _np 2192 dπ 0 π 0 over the energy region of the d * (2380) resonance by use of a polarized deuteron beam and observing the double fusion reaction in the quasifree scattering mode. The measurements were performed with the WASA detector setup at COSY. The data reveal substantial analyzing powers and confirm conclusions about the d * resonance obtained from unpolarized measurements. We also confirm the previous unpolarized data obtained under complementary kinematic conditions. |
