Phys. Rev. A 69, 042515 (2004) [5 pages]Accurate S-state helium wave functions in momentum spaceReceived 22 January 2004; published 26 April 2004 High-accuracy helium wave functions based on exponentials with random coefficients are transformed into momentum space. The utility of the wave functions is demonstrated through calculation of the expectation value of various operators needed to evaluate relativistic and QED corrections. © 2004 The American Physical Society URL:
