Astrochemical models play a crucial role in interpreting studies of interstellar and circumstellar molecules, providing insight into the gas's physical properties and evolution. Advances in astrochemical models are linked to changes in databases and rate coefficient estimations, both experimental and theoretical (see e.g. Iacob et al. 2019; Albert 2020; Srećković et al. 2022; Srećković et al. 2023; Vujčić et al. 2023). The science community requires access to preferred molecular data for modeling and understanding the chemistry of planet formation. Atomic and molecular datasets, such as VAMDC, are essential for developing models and simulations. The examination of studied rates offers useful insights into the occurrence of species. Research should focus on both radiative and concurrent processes involving molecular ions, including dissociative recombination. Our goal is to calculate, evaluate, and analyze cross sections and rate coefficients for molecular ions like hydrogen and helium using different model parameters.
