The classical methodology incorporates two active electrons in the target, offering insights into double capture, double ionization, and capture-ionization. Additionally, we apply numerical solutions of the time-dependent Schrödinger equation to ion collisions with small molecules, constructing effective potentials. Notable systems, including H2O, uracil, and other nitrogen bases relevant to proton therapy, undergo rigorous study.

At lower collision energies (10 to 1000 eV/u), ab initio quantum mechanics methods come into play, especially in collisions involving protons with urea, furan, and uracil molecules. We explore the electronic structure of ion-molecule systems, identifying relevant electronic states and non-adiabatic couplings. This data informs the time-dependent wave function of collisional systems, considering diverse ion-molecule trajectories to accommodate molecular anisotropy.
