Abstract

There is strong evidence that the nucleus ${}^{222}{Ra}$ displays both quadrupole and octupole permanent deformations. The observed energy splitting between the associated even- and odd-parity rotational bands can be described in terms of superfluid tunneling in the space of nuclear shapes.
