ARSENY: A Program for Computing Inelastic Transitions Via Hidden Crossings in One-Electron Atomic Ion–Ion Collisions with Classical Description of Nuclear Motion / A.A.Gusev, E.A.Solov'ev, S.I.Vinitsky // Computer Physics Communications [Electronic resource]. – 2023. – Vol.286. – P.108662. – URL: https://doi.org/10.1016/j.cpc.2023.108662. – Bibliogr.:63.

The ARSENY program is intended to compute cross-sections of inelastic transitions via hidden crossings upon slow one-electron atomic ion–ion collisions using the approximation of classical description of nuclear motion in the collision energy region KeV/nucleon. Particular attention is paid to the calculation of the analytical properties of adiabatic potential energy curves of the two-center Coulomb problem for complex values of the internuclear distance. Complex branch points and hidden crossings are calculated and their significance for the dynamics of one-electron collisional systems is revealed. Benchmark calculations of cross sections for charge exchange, excitation, and ionization in slow He2++H collisions are presented and compared with experimental data.
