Abstract We use the two time influence functional method of the path integral approach in order to reduce the dimension of the coupled-channels equations for heavy-ion reactions based on the no-Coriolis approximation. Our method is superior to other methods in that it easily enables us to study the cases where the initial spin of the colliding particle is not zero. It can also be easily applied to the cases where there is a spin-orbit force, and where the internal degrees of freedom are not necessarily collective coordinates. It also clarifies the underlying assumption of the approximation.
