## Abstract

Our prime computation effort is to support current and future measurements of atomic photoionization cross-sections being performed at various synchrotron radiation facilities around the globe, and computations for astrophysical applications. In our work we solve the Schrödinger or Dirac equation using the R-matrix or R-matrix with pseudo-states approach from first principles. The time dependent close-coupling (TDCC) method is also used in our work. Finally, we present cross-sections and rates determined for diatom-diatom and radiative collision processes between atoms and ions currently of great interest to astrophysics.
