Tetrahedral correlations in 80Zr and 98Zr
Zberecki, K., Magierski, P., Heenen, P. -H. and Schunck, N. (2006) Tetrahedral correlations in 80Zr and 98Zr Physical Review C, 74 (5).
Axial octupole and tetrahedral correlations in 80Zr and 98Zr have been investigated using the generator coordinate method, applied to a basis generated by Skyrme Hartree-Fock+BCS calculations. We focus on the possible presence of states with tetrahedral symmetry and their stability with respect to octupole vibrations. We show that pairing significantly reduces the stability of the tetrahedral configuration and that a shallow mean-field tetrahedral minimum coexists with an axial octupole minimum. The contributions to the correlation energies coming from the tetrahedral degree of freedom and octupole axial deformation are discussed.
