β¦ Synopsis
Integrals over Slater atomic orbitais of the type ~&Jr) p; @b(~) d3r, where pi is a component of the linear momentum operaror, may be evaluated analytically by transforming the orbitak to momentum space. The procedure is a0 application of the Fourier convolution theorem. General farmdae are @en and uses for these integrals are suggested.

Using the Hi ion as an example, we discuss a fully numerical approach to the solution of the Hartree-Fock equation in momentum space which ensures accurate and stable solutions for polyatomic molecules. We made use of a "tangential" grid to solve the problems of truncation of momentum space and the
