Interaction anisotropy and vibrotational excitation in proton scattering from N-2((1)Sigma(+)(g))
Stimulated by the experimentally observed low vibrational inelasticity and the somewhat stronger rotational inelasticity in the H+-N-2 collisions, we present here a quantum dynamics study of the scattering process in the framework of vibrational close-coupling rotational infinite-order sudden approximation. We have employed the recently obtained ground-state potential-energy surface of the system from which both rotational and vibrational coupling potentials can be obtained. The various computed dynamical attributes such as differential and integral cross sections, and average vibrational as well as rotational energy transfers, are analyzed in detail and compared successfully with the available experimental results.
