      It is assumed that the dynamics of valence electrons of alkali-metal atoms can be well accounted for by a quantum-defect theoretic model while the core electrons may be supposed to move in a self-consistent field. This model is used to study the momentum properties of atoms from3Li to37Rb. The numerical results obtained for the momentum density, moments of momentum density and Compton profile are found to be in good agreement with the results of more detailed configuration-interaction calculations for the atom3Li. Similar results for11Na,19K and37Rb are compared with the corresponding Hartree-Fock-Roothaan values only, for want of data from other realistic calculations
