【Abstract】 The extended quark-delocalization, color-screening model (QDCSM) has been applied to the calculation of the mixing ratio of NN and ΔΔ in deuteron. The results agree with the experimental data, and the ratio is a little larger than other calculations. The possible reason is also discussed.更多还原
