Is the Eikonal Approximation Certainly Bad at Larger Angles?

  • The eikonal approximation is considered to be valid only for high energy and smaller angles.It is generally accepted that the eikonal approximation is certainly bad at larger angles.We show that the above view is a customary misunder-standing.

Abstract: The eikonal approximation is considered to be valid only for high energy and smaller angles.It is generally accepted that the eikonal approximation is certainly bad at larger angles.We show that the above view is a customary misunder-standing.
