• A formalism for high-energy multiple-scattering is developed, which is similar to the Glauber formalism but does not assume the eikonal approximation. The time-dependent scattering theory is adopted to generalize this approximation. In the eikonal approximation together with the adiabatic one, the time-dependent interaction Hamiltonian in the interaction representation turns out to be commutative. This commutative nature of the eikonal approximation enables us to propose a generalized approximation which assumes the commutativity itself. The extended approximation is called the generalized eikonal approximation (GEA) and is used to develop the extended multiple-scattering formalism. In the GEA the trajectory of the incident particle may deviate from the straight line, the trajectory adopted in the Glauber theory. Therefore, the extended formalism can be considered to be more reliable at large angles than the Glauber formalism.
