## Abstract Momentum expectation values (__p__^__k__^), values of the momentum density __P__(__p__) at selected points, and coefficients in the MacLaurin and asymptotic expansions of __P__(__p__) are used to test the quality of various orbital basis sets previously used for the atomic helium Hartre
