Abstract

Waveforms of electron pairs in superconductors are investigated on the basis of the atomic nature. According to the orbital function and a potential energy level for inner paired electrons in Thomas-Fermi-Dirac field, superconducting pairing states are determined by atomic number and radius. The s- and d-wave pairings dominate for superconducting atoms with atomic numbers (Z) less and more than 29, respectively. However, for exotic superconductors with crystal anisotropy and elemental superconductors of lacking crystal rigidity, when one wavefunction of multicomponent pair states crosses nodal surfaces of the orbital, the sign of the wavefunction changes, resulting in the appearance of p- and s-wave pairings for atoms with Z between 11 and 28, and more than 29, respectively.
