Electron Capture by B$^{5+}$ from H$_{2}$ At E $<$ 1.0 keV/amu

The capture of electrons from molecular targets has considerable influence on the charge state balance of astrophysical as well as magnetically confined fusion plasmas. Molecular targets are in general more complicated than their atomic counterparts. A suitable method by freezing the molecular details of the targets is applied with a core potential [1] that represents the ionic core of the target. The molecular orbital method, including the electron translation factor [2], in the impact parameter formalism [3] is employed to evaluate the state selective cross sections. The motion of the nuclei is treated classically and that due to electron is considered quantum mechanically [4]. Details will be presented at the conference. [1] J. N. Bradsley, \textit{Case Stud.
