    "abstract": "We study the ionization process involving antiproton and hydrogen in the\nenergy range between 0.1 keV to 500 keV, using single center close coupling\napproximation. We construct the scattering wave function using B-spline bases.\nThe results obtained for ionization of atomic hydrogen are compared with other\nexisting theoretical calculations as well as with the available experimental\ndata. The present results are found to be encouraging. We also employed this\nmethod to study the ionization of ionized helium in the energy range between 1\nand 500 keV. On comparision, the present results are found to interpret well\nthe cross section values calculated using other theories.",
