Structural Analysis of ²³ O Through Single-Neutron Stripping Reaction

Abstract

We have studied the single-neutron stripping reaction induced by 23O on carbon target at beam energy of 72 MeV/A with a motive to analyze its ground state structure. The partial stripping cross sections as well as longitudinal momentum distribution of 22O core have been calculated within the framework of the eikonal approximation approach. Several core-neutron spin coupling configurations, corresponding to Jπ = ½+ as ground state spin parity of 23O, along with their suitable admixtures have been considered. The major outcome of the present work is that the s and d admixed configuration with a large contribution of s state seems to explain the longitudinal momentum distribution data more satisfactorily.

Analysis of longitudinal momentum distribution data of core fragment coming from 9Be(11Be, 10Be+n)9Be stripping reaction

“…The depths of potentials are adjusted to reproduce the binding energy of the projectile. The binding energy of neutron in 11 Be is 0.504 MeV and the corresponding potential depth come out to be 61 MeV. The calculated LMD is compared with the corresponding experimental data taken from Ref.…”

“…Thus a lot of theoretical as well as experimental work has already been done to describe the stripping reactions involving weakly bound halo nuclei. [4][5][6][7][8][9][10][11][12] On the theoretical front, there are many theories of stripping reactions including semi classical diffraction theories, the coupled channel theory and the perturbation theory. However at high energy the eikonal approximation, developed by Glauber,13 is the most appropriate approach to describe the stripping processes at forward angle involving small momentum transfer.…”
