Abstract
The scattering of slow electrons and positrons by lithium metal dimer has been studied in the laboratory frame close coupling method. The effect of polarization is included through the parameter free model correlation potential given by Perdew and Zunger. In the case of electron, the exchange kernel is replaced by a local model exchange potential as used by Sur and Ghosh. To have a convergent result seven rotational states (j=0, 2, 4, 6, 8, 10, 12) are retained in the coupling scheme. The results for elastic, rotational and total cross sections fore − — Li2 ande + — Li2 are reported. The electron results are in fair agreement with measured values and existing theoretical predictions.
