The Nonresonant Charge Exchange subnode is available from the context menu (right-click the
Collisions parent node) or from the
Physics toolbar,
Attributes menu. The
Nonresonant Charge Exchange subnode causes particles to undergo charge exchange reactions with a background gas. Unlike the
Resonant Charge Exchange node, it is possible for the particle that undergoes the collision and the ionized and neutralized particles that result from it to be three different species. The ionized particle, neutralized particle, or both ionized and neutralized particles can be released.
See Elastic for information about the
Collision Statistics and
New Value of Auxiliary Dependent Variables sections.
These settings are the same as for the Elastic subnode with additional options to enter a value for the
Energy loss ΔE (SI unit: J), enter a value for the
Scattering angle in the center of mass system χ (SI unit: rad), and to select one of the following from the
Species to release list:
Ion (the default),
Neutral particle, or
Ion and neutral particle.
This section is available when Neutral particle or
Ion and neutral particle is selected from the
Species to release list. Select an option from the
Neutral properties list, which may be any
Particle Properties node that has been added to the physics interface.
