Tetrahedral Symmetry in nuclei: new predictions based on the collective model

Abstract : We apply the standard collective nuclear Hamiltonian derived in the literature with the help of the Adiabatic Time Dependent Hartree-Fock (ATDHF) theory. We use a schematic two-dimensional collective space spanned by the axial-quadrupole ( 20) vs. tetrahedral ( 32) deformations together with the potential energy surfaces calculated microscopically. We illustrate and discuss the collective-model solutions suggesting that the tetrahedral-symmetry nuclei may generate sizeable quadrupole transitions: this re- sult is in contrast to the previous expectations and/or predictions.
