Abstract
The close coupling approximation has been employed in positron-hydrogen molecule collision in the fixed nuclei formulation to obtain the electronic excitation cross section of the B 1 Sigma u+ state up to the incident energy 75 eV. The elastic cross sections are found to be influenced significantly when compared with the static results. The effect of the excited state on the elastic channel enhances the elastic cross section. In the absence of any other theoretical results or measured values, excitation cross sections are compared with the corresponding electron results.
