Introduction
The role of antisymmetry requirement of wave functions in the structure
of many-electron system configurational space (atoms and molecules,
including their excited states [7]) is shown in [1-6]. One of
the consequences of this requirement is prohibition for electrons to
take some spaces in physical space with zero value of the wave function.
These positions of electrons determine some nodal surfaces in
configurational space, which divide the space to N ! (N ! =
1∙2∙3∙…∙N ) equivalent areas for atoms and molecules withN electrons. The equivalence means that, in case we receive the
solution of Schrödinger equation (Ψ function) for one such area, the
solution for the rest of them is received simply by permutation of the
electron indices [8]. In the same article [8] it is shown that
some unknown fundamental physical forces called antisymmetry forces by
us must exist. Specifically they forbid to electrons to take the
positions mentioned above and characterized usually by some symmetry. In
paper [9] the hypothesis was offered that the wave function turns to
zero for configurations with equal potentials of any two electrons with
the same spins. This hypothesis was proved with calculations for He, Li
and Be atoms and for molecules H2 in triplet state and
LiH [10, 11]. In the present paper same foundation of our hypothesis
is given.
