dissociativeIonizationWorks with a VSimPD license. Collision of the form
or
A generator of 4 product particles, two atoms that have been dissociated and two electrons: one that impacted to cause the ionization and other from the ionization caused the dissociation. Double ionization is achieved by including a third electron product and a second ionized atom in a the Reactants and Product vectors in the RxnProcess Block
Any RxnProcess Block block which points to a
productGenerator of kind = dissociativeIonization should have the
Reactants and Products in the order
reactants = [AB electron]
products = [ionizedA (ionized)B electron electron (electron)]
dissociationEnergy(float, required)The energy required to dissociate the molecule, in eV. This value also sets a threshold for whether or not the reaction will occur. So a pair of particle will need at least this much relative energy (i.e. energy in center of momentum frame) in order to react. This can be set as a negative value to have the products gain kinetic energy.
randomSeed (int, optional, default: random int)Manually set a random seed used to determine the final velocities of the product particles.
The default is to choose a random seed at run time. To produce identical simulations, advanced users may want to manually set a seed. It is recommended not to include this parameter so that a different random number will be generated for each run.
