We have computed excitation cross section (ECS) of inert gas atom (Krypton) by impact of positron and electron using close coupling approximation method. High quality Hartree-Fock Slater orbitals are used to model the target wave function. We have already computed the excitation results1,2 for inert gas atoms (Ne, Ar, Kr, and Xe) by positron as well as electron impact, but in this paper, we are presenting for Krypton atom only. Full orthogonalization significantly improves agreement with experimental data for the noble gas series. We have compared ECS results with other available theoretical results as well as experimental data. Our present results are found in excellent agreement with other calculations. However some discrepancies suggested that more theoretical as well as experimental work is required in future to improve the data.
