【 摘 要 】

We have studied isospin symmetry violation in nuclear reactions by measuring simultaneously the cross-section of the following two reactions 𝑝 + 𝑑 → 3H 𝜋+ and 𝑝 + 𝑑 → 3He 𝜋0. The experiment was perfomed at the cooler synchrotron accelerator. COSY, Jülich at several beam energies close to the corresponding 𝜂 production threshold. We also have ongoing programmes on 𝜂-nucleus final-state interaction studies via 𝑝 + 6Li → 7Be + 𝜂 reactions, high resolution search for dibaryonic resonances and lambda-proton final state interaction studies. The experimental details and results obtained so far are presented here.
