Development and Applications of the Semiclassical Theories for Nonadiabatic Transitions and Tunneling Phenomena

1)对于有望成为Landau-Zener-Stueckelberg型和Rosen-Zener-Demkov型非绝热跃迁统一理论的指数势模型，我们已经很好地完成了分析工作(已发表的文献1、2和5)。2)利用朱-Nakamura理论，很好地再现和分析了共线0HO*OH0反应中非常尖锐的Feshbach型共振(发表论文3)。3)用超球坐标方法计算了氢转移反应ClHBr*HCI-BR的量子动力学，并根据势脊和振动非绝热跃迁阐明了反应机理(发表论文4)。

1)Concerning the exponential potential model which is expected to be a good candidate of a unified theory to cover both Landau-Zener-Stueckelberg type and Rosen-Zener-Demkov type nonadiabatic transitions, we have accomplished analytical works to a very good extent (published papers 1, 2, and 5).2)With use of the Zhu-Nakamura theory, very sharp Feshbach type resonances in the col1inear 0 + HO* OH + 0 reaction have been nicely reproduced and analyzed (published paper 3).3)Quantum dynamics of the hydrogen transfer reaction Cl + HBr * HCI + Br have been calculated with use of the hyperspherical coordinate approach, and the reaction mechanisms were clarified in terms of the potential ridge and vibrationally nonadiabatic transitions (published paper 4).
