Peer reviewedSnow, Richard L.; Bills, James L. – Journal of Chemical Education, 1974
The authors indicate that several recent textbooks in quantum chemistry use a discussion of the excited states of the helium atom to demonstrate the importance of the Pauli principle in determining electronic repulsions. They present data suggesting "Pauli forces" do not keep electrons of parallel spins separated in space. (RH)
