Convolution Approximation Method (CAM) for Energy Loss of Cluster Ions

Electronic energy loss of molecular cluster as a function of impact parameters is less understood than atomic energy loss. Vicinage effect due to mutual interference between cluster fragments play a key role in the determination of the cluster electronic energy loss. In present work we used Hydrogen di-cluster ions in Hydrogen using three kinds of potentials, Coulomb, Bohr and single-zeta potentials at different orientations. Good agreement between molecular perturbation convolution approximation (MPCA), dipole and close collisions at impact parameter p £ 2 .
