We present simulation results for the one-dimensional random deposition of two annihilating species A and B, falling with probabilities p and q (p1q51), which then react to produce an inert product, i.e., A1B!0. Two different annihilation rules are defined: top annihilation and nearest-neighbor annihilation ~NNA!, leading to distinct scaling behaviors. In particular, the values of the scaling exponents for NNA are found to be dependent on probability p, suggesting different universality classes.A and B, falling with probabilities p and q (p1q51), which then react to produce an inert product, i.e., A1B!0.
