Observation and dynamic control of a new pathway of H₃⁺ formation

The "Potential Energy Surface" file is the calculated potential energy surface data for D2 dimer (shown in Fig. 1a). The files "1D_Center-of-mass-distance_D2_Dimer" and "2D_Center-of-mass-distance_D2_Dimer" are the simulation trajectories for D2 dimer (shown in Fig. 1b). The data file "D3+_Yields_Delay" shows the calculated yield (without normalization) of D3+ as a function of time delay. We also did the same calculations on H2 dimers, and the data files are "1D_Center-of-mass-distance_H2_Dimer", "2D_Center-of-mass-distance_H2_Dimer", and "H3+_Yields_Delay", respectively. The measured time-of-flight spectrum is in the data file "TOF". The measured photoion-photoion coincidence (PiPiCo) spectrum is in the data file "PIPICO". The measured yields of the three different channels (D3+ + D, D3+ + D+, and D2+ + D2+) are in the data file "yield_3channels".
