The effects of various parameters on the interaction of two galaxies and on the gas cloud collisions which are induced to occur are considered by examining several simulations of an interaction with different impact parameters, similar to the simulations described by Olson and Kwan (1990). The results of the present calculations are consistent with those obtained earlier by Olson and Kwan. They show that the interaction of two galaxies can lead to an increase in the rate at which gas clouds collide, and that these collisions are of sufficient kinetic energy to disrupt the clouds and prevent the buildup of a large number of massive clouds. It was found that, as the inclination of the interaction is increased, the perturbation of the cloud system is decreased. It was also found that unbound orbits produce a smaller perturbation than bound orbits, and that decreasing the mass of the perturbing galaxy decreases the perturbation.
