Abstract: We prove that the ground state momentum distribution of a one-dimensionalsystem of impenetrable bosons exhibits a $k^{-4}$ tail for any confiningpotential. We also derive an expression for easily computing the asymptoticoccupation numbers and verify our results with an exact numerical approach.
