CDW-EIS calculations deliver a database of atomic ionization cross sections for about 130 projectile-target systems, with a neural-network surrogate extending coverage to systems not calculated directly
The authors performed ab initio continuum distorted-wave eikonal initial-state (CDW-EIS) calculations of atomic ionization for targets from H to Kr under bare-ion and antiproton impact, released a public database of 6239 subshell-resolved total ionization cross sections across about 130 projectile-target systems, and trained a five-member neural-network surrogate, CDWEIS-NN, to interpolate and predict projectile-target combinations and impact energies not calculated directly.
