Abstract: Abstract Our prime computational effort is to support current and future measurements of atomic photoionization cross-sections at various synchrotron radiation facilities, and ion-atom collision experiments, together with plasma, fusion and astrophysical applications. We solve the Schrödinger or Dirac equation using the R-matrix method from first principles. A time-dependent close coupling approach is used to investigate ion-atom excitation and electron-impact ionization. Finally, we present cross-sections and rates for molecule-molecule interactions and radiative association reactions between atoms of interest in astrophysics.
