Query: Theoretical Study of Quantum Scattering Processes for Diatomic Hydrogen
  $(^{2}S)$ and Oxygen $(^{3}P)$ Complex   We present a quantum mechanical study of the diatomic hydrogen $H(^{2}S)$ and
oxygen $O(^{3}P)$ collision and energy transfer for its four molecular symmetry
$(X^{2}\Pi, ^{2}\Sigma^{-}, ^{4}\Pi, ^{4}\Sigma^{-})$, which is important for
the investigation of many processes of astrophysical and chemical interests
including the one on molecular cooling, trapping or Bose-Einstein condensation.
We compute the rovibrational spectra for the $(X^{2}\Pi)$ state and the
resulting bound states are in an excellent agreement with experimental data for
the energy range lower than the dissociation threshold. We calculate the phase
shifts of its partial-waves, the total cross section, and the differential
cross section. They are all well-structured because of the shape of its
potential curve. We do the similar studies for the other three dissociative
states $(^{2}\Sigma^{-}, ^{4}\Pi, ^{4}\Sigma^{-})$. Finally, we have also
decided the thermal rate coefficients for the hydrogen and oxygen collision for
its four individual states.
