The properties of momentum distribution in neutral atom He, Ne, Ar, Kr and Xe are studied in this paper under the condition of impulse approximation. In particular, we have calculated the single-electron momentum density distribution of all sub-shell electrons and the Compton profile for ground-configurations 1s~2, 1s~22s~22p~6, 1s~22s~22p~63s~23p~6, 1s~22s~22p~63s~23p~64s~23d~(10)4p~6, 1s~22s~22p~63s~23p~64s~23d~(10)4p6~5s~24d~(10)5p~6 of He,Ne,Ar, Kr and Xe, respectively. The single-electron radial wave functions in coordinate space are obtained from Hartree-Fock with relativistic Corrections (HFR) method. And, the associated momentum space wave functions are calculated by applying appropriate Fourier transformation. The results of Compton profile computed in this paper are in excellent agreement with the experimental or theoretical values available in the literature. It is expected that this study are helpful for interpreting the experimental cross-sections for above atom colliding with other excited ions.
