Charge Exchange in O$^{7+}$+H collisions

Charge exchange between heavy solar wind ions and interstellar neutrals is thought to be a dominant contributor to the heliospheric component of the soft x-ray background, as the highly charged resultant ion emits an x-ray photon through the electron's cascade to the ground state. In this study we calculate $n-$, $l-$, $S- $resolved charge capture cross sections into the dominant $n=4$, 5 and 6 manifolds for the system O$^{7+}$+H, over a range of collision energies 0.01-50 keV/u, using the molecular orbital close coupling method. We compare our results with classical trajectory Monte Carlo, atomic orbital close coupling, and experimental results.
