Dissociative Recombination¶
Works with a VSimPD license. Collision of the form
Any RxnProcess Block block which points to a
productGenerator of kind = dissociativeRecombination
should have the
Reactants
in the order:
reactants = [speciesABplus electron]
Note
The second reactant is not required to be an electron. The order of the products can be arbitrary.
dissociativeRecombination Attributes¶
- thresholdEnergy (float, required)
The threshold energy for the reaction in eV. So, a pair of reactants will need at least this much relative energy (i.e. energy in center of momentum frame) in order to react. If the reaction occurs then this much energy is lost from the products to potential energy. If this is zero, then energy will not be lost. If negative, then the products will gain kinetic energy.
- anisotropy (float, optional, default = 0)
A value between -1 and 1 to set the degree of anisotropy. An anisotropy of -1 is full backscatter, 0 is isotropic, and +1 is full forward scatter.
- 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.
Example dissociativeRecombination Block¶
<RxnProductGenerator productGenerator>
kind = dissociativeRecombination
thresholdEnergy = 1.0
#anisotropy = 0
#randomSeed = 423
