Helium momentum-space wave function and Compton profile
Abstract
This paper describes an effort to develop further the work of R. McWeeny and C. A. Coulson [Proc. Phys. Soc. London, Sect. A 62, 509 (1949)] to obtain a helium-atom ground-state wave function in momentum space. In the application of Svartholm's method [N. V. Svartholm, Ph.D. thesis, University of Lund, Sweden (1945)] to the helium momentum-space integral Schrödinger equation, a Feynman-integral evaluation technique is used to start the iteration in the electron-electron interaction term. The resulting correlated momentum-space wave function is used to evaluate the helium-atom ground-state energy and Compton profile.
