The UK Molecular R-Matrix codes are a set of software routines used to calculate the effects of collision of electrons with atoms and molecules.
The R-matrix method is used in computational quantum mechanics to study scattering of positrons and electrons by atomic and molecular targets.
The UK Molecular R-Matrix codes were developed by the Collaborative Computational Project Q (CCPQ).
[3] Quantemol-N (QN) is software that allows the UK molecular R-matrix codes, which is used to model electron-polyatomic molecule interactions, to be employed quickly with reduced set-up times.
QN is an interface that simplifies the process of using the sophisticated UK molecular R-Matrix codes.
