Study of Coulomb nuclear interference in ¹²N nucleus breakup reaction

We investigated the Coulomb-nuclear interference effect on a single proton removal cross-section and full width at half maximum (FWHM) of longitudinal momentum distribution (LMD) in the breakup reaction of a proton rich 12 N nucleus.The effect is analyzed for three different targets: 12 C, 58 Ni and 208 Pb nucleus, in 40-100 MeV/u incident beam energy range.The Coulomb breakup mechanism is treated with all-order sudden approximation, while the nuclear breakup, including both stripping and diffraction is treated using eikonal approximation.The obtained results show that the interference among breakup mechanisms significantly affects the single proton breakup cross-section, more specifically in medium-mass target cases.However, the effect is found to be below 6% for FWHM of LMD for all the chosen targets.The obtained results show that in mediummass targets reactions, it is crucial to consider the interference between the Coulomb and diffraction breakup processes for 40-100 MeV/u energies.We believe that this understanding of the obtained results will be valuable for planning future experiments involving proton halo nuclei and also add better clarity in the interpretation of experimental results.
