Abstract
The impact of nuclear deformation and effective mass on the momentum distributions (MD) of occupied proton states in is investigated in the self-consistent Skyrme-Hartree-Fock (SHF) scheme with parameterizations SkT6, , SLy6, and SkI3 as well as with the phenomenological Woods-Saxon (WS) shell model. The deformation effect turns out to be significant in the low-momentum domain of states (mainly of those lying near the Fermi surface) and negligible for other states. The most remarkable result is that all Skyrme parameterizations (with essentially different ) and the WS potential give very similar MD. This means that the value of effective mass, although crucial for single-nucleon spectra, is not important for the spatial shape of the wave functions and thus for the MD. For the description of MD at , one may use any single-particle scheme fitted properly to the global ground state properties.
