Abstract: Robust control of atomic coherence and population transfer among Zeeman sublevel s in the ground states of atom is investigated theoretically using adiabatic rap id passage on a nanosecond time scale. It is shown that a slight change in the p ump pulse time delay relative to the Stokes pulse leads to a significant modific ation of atomic coherence and population transfer. This coherence control of qua ntum state and population is presented by numerical simulations based on self-co nsistent set of density matrix equations and Maxwell equations.
