Spin-polarized quantum systems

An extension of de Boer's quantum theorem of corresponding states, applicable beyond the usual thermodynamic properties, is realizable when Hall-Post-Stenschke lower-bound energies are matched with the experimental internal energies of the condensed phase of spin-polarized quantum systems and rare-gas atoms. Through it is found evidence that both forms of spin-polarized deuterium have bound ground states, that spin-polarized helium has an internal energy of -2.10K per atom and that the minimum number of atoms required in a cluster so that it behaves like the bulk system ranges from 6 to 19.
