本文报道了在准自由散射模式下，利用极化氘束对最基本的双π熔合反应$\overrightarrow{n} p\rightarrow d\pi^{0}\pi^{0}$在~*（2380）共振能区的高统计测量.使用COSY的WASA检测器进行测量。这些数据揭示了大量的分析能力，并证实了从非极化测量获得的d* 共振的结论。我们还确认了以前的非极化数据下获得的互补运动学条件。
We report on a high-statistics measurement of the most basic double-pionic fusion reaction $\overrightarrow{n} p\rightarrow d\pi^{0}\pi^{0}$ over the energy region of thed*(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.
