![]() ![]() By comparing the cross-sections of three oxygen isotopes, we find that the heavier isotopes consistently have larger collision cross-sections than the lighter isotopes. ![]() ![]() Our differential cross-section results indicate a strong preference for forward scattering over sideways or backward scattering, and this anisotropy in scattering is further pronounced at higher collision energies. We conducted a series of quantum scattering calculations between various isotopes of O( 3 P) atoms and N 2 molecules across a range of collision energies (0.3–4 eV), and computed both their differential and collision cross-sections using quantum time-independent coupled-channel approach. In this work, we investigated the elastic and inelastic collisions between hot oxygen atoms and neutral N 2 molecules, relevant to oxygen gas escape from the Martian atmosphere and for characterizing the chemical reactions in hypersonic flows. Thermalization of hot atoms is mainly governed by the amount of species present in the surrounding atmosphere and the collision cross-sections between the hot atoms and surrounding species. This process (known as thermalization) plays a crucial role in various astrophysical and atmospheric processes. ‘Hot atoms’, atoms in their excited states, transfer their energy to the surrounding atmosphere through collisions. ![]()
