The collective states of Ra are used as input for a phenomenological model based on an axial quadrupole–octupole Bohr Hamiltonian, to determine its shape and the nature of the excited band. The later is interpreted by two competing excitation mechanisms for which distinguishing spectral signatures are forwarded. The ground state is found to have a well stabilized equilibrium quadrupole–octupole deformation. Its corresponding shape is correlated with a molecular state encountered along the disintegration path predicted within a microscopic–macroscopic model.
