The ground state structure of $^{29}$Ne [1,2,3] has been comprehensively examined by analyzing different observables of nuclear breakup, $^{12}$C($^{29}$Ne, $^{28}$Ne+n)$^{12}$C, reaction at 240 MeV/u beam energy by employing the Glauber approach using the Abu-Ibrahim [4]. Here, we have considered all possible core-neutron spin coupling configurations and their appropriate admixture to represent the ground state of $^{29}$Ne. It is found that both the reaction ($\sigma_{-R}$) as well as the one-neutron removal cross section ($\sigma_{-1n}$) are well explained by considering $[0_1^+ \otimes 2p_{3/2}]$ [3,5] as the core-neutron spin coupling configuration with $J^\pi = \frac{3}{2}^-$ for $^{29}$Ne. However, the spectrum of inclusive longitudinal momentum distribution (LMD) of $^{28}$Ne core residues is better described by considering the admixture of p and f states with 0.8 and 0.2 as the spectroscopic factors corresponding to $J^\pi = \frac{3}{2}^-$.
