Octupole correlation energy

From a microscopic point of view, octupole deformation in even-even nuclides is signalled by (r and 0 bands that have the same properties. This implies a ground state rotational band with alternating even and odd parity states, i.e. 0+, 1, 2+,. Such ground state bands have not been found in any nuclides to date. In Fig. 2, we show the results of a microscopic calculation of octupole correlation energies in the 0+ and the 1 states of Ra...
