We report the experimental observation of temporal quantum interference between two time-delayed 3S-3P-5S (or 4D) transition pathways created through two collision-assisted two-step excitation processes by using a single nanosecond laser pulse in the Na{sub 2}-Na system. It is clearly shown that the collisions offer a promising alternative to realize quantum interference in the time domain at room or higher temperatures despite the dephasing nature.
