Three-body Effects in the Fragmentation of D2 by Slow, Highly-charged Xenon

Abstract

Fragmentation of D2 by slow Xe26+ ions is studied using multi-hit, position-sensitive detection of both D+ fragments. By detecting both ion fragments, kinematically complete pictures of the breakup dynamics following double electron removal are obtained. These data are compared to 5-body CTMC calculations. For slow collisions, two types of three-body effects are identified. The largest is attributed to interactions between the undissociated molecule and the dipole field of the projectile and is compatible with a two-step fragmentation picture. A smaller effect, attributed to quadrupole-like and higher multipole interactions between the dissociating fragments and the projectile field is also observed. This "true" 3-body effect, extracts internal energy from the exploding molecule and is incompatible with a two-step picture.
