Abstract： Introducing a theoretical method to treat time-dependent wave-packet dynamics for atom collisions, we calculate the cross sections of proton impact excitation (2s - 2p) with a Li atom by directly numerically integrating the time-dependent Schrödinger equation on a three-dimensional Cartesian mesh. Our calculated results are in good agreement with the available experimental measurements.
