Table : List of parameters defining: the initial nuclear wavepacket, via γ 0 and x c ; the system and the potentials, via the mass m and a, α, V 0 for the Eckart barriers or b, d for the ramp; the numerical procedure for the TDQT propagation, via the ODE error tolerance and the number of trajectories; the numerical procedure for the Crank-Nicholson integration via the grid boundaries, the spacing dx and the time step dt. For the symmetric and asymmetric Eckart potentials, several calculations were performed by increasing the initial kinetic energy as indicated in Fig. ; for the potential ramp, four
