The long-time behavior of scattered wave packets {psi}(x,t) from a finite-range potential is investigated, by assuming {psi}(x,t) to be initially located outside the potential. It is then shown that {psi}(x,t) can asymptotically decrease in the various power laws at long time, according to its initial characteristics at small momentum. As an application, we consider the square-barrier potential system and demonstrate that {psi}(x,t) exhibits the asymptotic behavior t{sup -3/2}, while another behavior like t{sup -5/2} can also appear for another {psi}(x,t)
