Description

Lattice Hartree-Fock + BCS calculations for axially asymmetrical solutions have been extended to heavy nuclei. The deformation energy surfaces in a (β,γ) sextant for the 138Sm and 192Os nuclei exhibit a shallow triaxial minimum, while a valley connecting smoothly the oblate and prolate minima is found in the 186Pt nucleus.
