Abstract
In many areas of atomic, molecular and nuclear physics one needs to evaluate highly oscillatory integrals of the form, where f, g, V ∈ C and where V has a singularity no worse than l/|r 5 + r f|. With the advent of the 6 Dimensional Integral Method, (6DIME) it is now possible to numerically evaluate any integral of the form (1) if g is a bounded function1. This method has already been applied successfully to (e,2e) processes on H,2 and H−,3 targets. In this paper we will demonstrate the applicability of the 6DIME to the calculation of (7,2e) in which a linearly polarised photon ionises both electrons from a Helium atom. The two exiting electrons are detected in coincidence, thus providing one with a complete kinematical description of the collision.
