本文报道了CO（j=0）+ H2（j= 0）→ CO（j=1）+ H2（j=0）系统的交叉束实验和量子力学计算。在CO（j=0 → j=1）跃迁阈值区3.85cm（-1）处测定的实验截面表明，共振结构与理论结果定性一致.这些结果表明，描述CO-H2货车范德华相互作用的势能面应该重新研究，以获得良好的定量一致性。
We report on crossed-beam experiments and quantum-mechanical calculations performed on the CO(j=0) + H2(j=0) → CO(j=1) + H2(j=0) system. The experimental cross sections determined in the threshold region of the CO(j=0 → j=1) transition at 3.85 cm(-1) show resonance structures in good qualitative agreement with the theoretical ones. These results suggest that the potential energy surface which describes the CO-H2 van der Waals interaction should be reinvestigated for good quantitative agreement.
