Nuclei with Tetrahedral Symmetry
Received Revised We discuss a point-group-theory based method of searching for new regions of nuclear stability. We illustrate the related strategy with realistic calculations employing the tetrahedral and the octahedral point groups. In particular, several nuclei in the Rare Earth region appear as excellent candidates to study the new mechanism.
متن کاملAtomic Nuclei with Tetrahedral and Octahedral Symmetries
We present possible manifestations of octahedral and tetrahedral symmetries in nuclei. These symmetries are associated with the O h and T d double point groups. Both of them have very characteristic finger-prints in terms of the nucleonic level properties unique in the Fermionic universe. The tetrahedral symmetry leads to the four-fold degeneracies in the nucleonic spectra; it does not preserve...
متن کاملNuclear Tetrahedral Symmetry
It has been recently pointed out that atomic nuclei with tetrahedral symmetry could be encountered all over the nuclear chart. The predictions are based on a very general analysis of symmetries of the nuclear mean-field and are inspired by the group-theory considerations. The implied unique 4-fold degeneracies of the single-particle levels characteristic of tetrahedral (and/or octahedral) symme...
متن کاملChiral Symmetry in Nuclei
The impact of chiral symmetry on nuclear physics is discussed in the context of recent advances in the few-nucleon systems and of dimensional power counting. The tractability of few-nucleon calculations, illustrated by very recent solutions for A = 2 − 6, is shown to follow from power counting based on chiral Lagrangians. The latter predicts the suppression of N -body forces, as originally show...
متن کاملA Relativistic Symmetry in Nuclei
We review the status of a quasi degenerate doublets in nuclei, called pseudospin doublets, which were discovered about thirty years ago and the origins of which have remained a mystery, until recently. We show that pseudospin doublets originate from an SU(2) symmetry of the Dirac Hamiltonian which occurs when the scalar and vector potentials are opposite in sign but equal in magnitude. Furtherm...
