✦ Synopsis

The momentum averaged Gaussian-weighted (MAGW) method that was introduced by Bawagan and Brion for incorporating experimental momentum resolution effects into theoretical momentum distributions and defining the momentum scale in EMS experiments is extended to use a three-dimensional collision volume. Using this three-dimensional model, the effects of varying the impact energy are investigated. It is found that the impact energy affects the momentum resolution and the momentum scale dramatically, especially at low momentum values.
