In this paper the main attention has been given mainly on the projectile energies of ionic nitrogen in collision between atomic hydrogen as target in intermediate and high energies. Boundary Corrected Continuum Intermediate State Approximation (BCCIS) formulism has been taken to study the present problem. Theoretical calculation using quantum mechanics has been taken into account in this formulism. The important feature of this method lies in the fact that proper boundary condition is satisfied and intermediate continuum states are accounted properly into the formalism. It may easily be extended to non-coulombic potential as well. We have calculated the charge transfer collision cross sections for different degree ions of nitrogen from atomic hydrogen by reducing the charge exchange amplitude to arbitrary states to a one dimensional integral form. Projectile energies are limited in between 40 keV/ amu and 200 keV/ amu in the present work. Cross sectional data of charge transfer of the collision problem have been given in graphical representation. The calculated cross sections are in good agreement with the other experimental theoretical and experimental available results. The success of the present investigation lies on the fact that the careful construction of the model potential in such a way that the potential parameters are unambiguously determined on imposing several checks. It may be pointed out that in such a formulation the dynamic correlation of the active electrons is absent. Only the static correlations of the electrons have been included. However, the charge transfer dynamics at low energies is very complex even on quantum mechanical framework. Collisions cross sectional data are important in studies of reactors, explanation of astrophysical phenomenon, investigation of ionization radiation and high energy particle transport in inertial controlled fusion (ICF) radiobiology.
