Charge exchange integral cross-sections of protons colliding with deuterium atoms have been calculated from the energy range 5keV to 5MeV. The differential cross-sections have been calculated in the angle ranging from 0-4 mrad. We have employed the Coulomb-projected Born approximation to obtain differential as well as integral cross-section for the system H+ + D(1s) under study.

Abstract


Charge exchange integral cross-sections of protons colliding with deuterium atoms have been calculated from the energy range 5keV to 5MeV. The differential cross-sections have been calculated in the angle ranging from 0-4 mrad. We have employed the Coulomb-projected Born approximation to obtain differential as well as integral cross-section for the system H+ + D(1s) under study.
