英文摘要 | Theory has established the importance of geometric phase (gp) effects in the adiabatic dynamics of molecular systems with a conical intersection connecting the ground- and excited-state potential energy surfaces, but direct observation of their manifestation in chemical reactions remains a major challenge. here, we report a high-resolution crossed molecular beams study of the h + hd -> h-2 + d reaction at a collision energy slightly above the conical intersection. velocity map ion imaging revealed fast angular oscillations in product quantum state-resolved differential cross sections in the forward scattering direction for h-2 products at specific rovibrational levels. the experimental results agree with adiabatic quantum dynamical calculations only when the gp effect is included. |
