我们计划对12 C（p，dp）反应进行半排他的测量，以寻找β '介子核，从而研究β'介子的介质内性质.我们用2.5GeV质子束轰击碳靶，通过12 C（p，d）π π使用符合测量的前向去氘核，重要的失踪质谱，和衰变质子发射的β '-介子核。事件选择将提供高的实验灵敏度来观察β ′-介子核。我们将通过将WASA探测器系统与GSI的碎片分离器FRS以及未来FAIR的Super-FRS相结合来进行测量。报告了实验计划和现状。
We plan a semi-exclusive measurement of the 12 C (p, dp) reaction to search for η'-mesic nuclei, aiming at investigating in-medium properties of the η'-meson. We employ a 2.5 GeV proton beam impinging on a carbon target to produce η'-mesic 11 C nuclei via the 12 C (p, d) η'⊗ 11 C reaction. Using coincidence measurements of the forward going deuterons, important for missing-mass spectroscopy, and decay protons emitted from the η'-mesic nuclei. for event selection will provide a high experimental sensitivity to observe η'-mesic nuclei. We will perform the measurements by combining the WASA detector system with the fragment separator FRS at GSI and also with the Super-FRS at FAIR in the future. The plan of the experiments and the present status are reported.
