Quantemol-EC is a new generation highly automated software to calculate electron-molecule scattering cross sections using a suite of new R-matrix codes. The QEC python GUI interfaces to both the Molpro quantum chemistry package for molecular target setups and the sophisticated UKRmol+ codes to generate accurate and reliable cross-sections

Quantemol-EC is offering additional features to Quantemol-N software:
– V1 (2019):

  • automatic generation of configurations
  • automatic detection of symmetry
  • automatic handling of degenerate states
  • more accurate ionisation crosssection calculations
  • summary with the results and the level of theory used to generate the results in order to help your understanding and publication
  • access to the most recent version of R-matrix code

– V2: dissociative recombination estimations and branching ratio estimations. (2020)
– V3: vibrational excitations for ions (2020)
– V3: effective core potentials (2020)
– V4: vibrational excitations for neutrals (2021)
