Studies of the $\eta$ meson with WASA at COSY and KLOE-2 at DA$\Phi$NE 。
The experimental data of the COSY-GEM collaboration for the recoil-free transfer reaction p(27Al,3He)π−p′X, leading to the formation of bound state of eta (η) meson in 25Mg nucleus, is reanalyze...
Dibaryon Signals in NN Scattering Data and Further Measurement at COSY, LEPS and CSR
nucleonnucleon scattering dibaryon quark model
2009/10/29
The NΔ and ΔΔ dibaryon resonances are studied by calculating the NN scattering phase shifts with explicitly coupling these dibaryon channels in a multichannel coupling calculation with two quark m...
Luminosity determination for the dd→α K+K－ experiment at ANKE/COSY
luminosity ANKE dd(quasi-)elastic
2009/8/14
High resolution studies of a0/f0(980) decays into channels involving open strangeness are currently being performed at COSY-J\"ulich. As a "filter'' for isospin-zero intermediate states, {i.e.} to se...
昆明山海棠（TriPtcryglum hJPOglaucum）的生物碱可从甲醇中结晶析出，多元混合物。高压液相色谱分析出现5个峰，用制备性烷化硅胶RP－18薄层层析板分离纯化，5个生物碱逐一分开。用化学和光谱法证明为：雷公藤次碱、雷公藤碱乙、雷公藤碱丁、雷公藤碱及卫矛碱（1一5）。高压液相色谱分析指出，前二者为其中的主要成分。用高分辨核磁共振谱及COSY 指定了它们的质子及其在分子中的取向，说明了...
