In this work, we simulate the laser-induced photoassociation of the collision reaction O+H to generate the OH molecule. The photoassociation process involves the continuum-discrete transition, and the initial wavepacket corresponding to the collision pair is generally given by a superposition of continuum state. By numerically solving the Schroedinger equation with split-operator method, we can take into account implicitly but completely for the continuum state in the photoassociation process. In our simulation, we find interestingly the above threshold dissociation spectrum due to the continuum-continuum transition as well as the target bound states by the photoassociation. In order to analyze the continuum state involved, we show the effective method by means of the quasicontinuum state on the Morse potential obtained by numerically diagonalizing the total system.
