  We study the cluster emission properties of 224Ra and 238Pu employing the
Barcelona-Catania-Paris-Madrid (BCPM) energy density functional (EDF). Starting
from two-dimensional potential energy surfaces, coexisting fission paths are
identified. A fission valley located at large octupole deformations,
corresponding to a highly-asymmetric mass distribution, is found in both
nuclei. As the corresponding fragments are dominated by the presence of 208Pb,
we can relate this fission path to the emergence of cluster emission. Using the
octupole moment as collective degree of freedom, we compute the cluster decay
half-lives and study the impact of collective inertias, pairing strength and
collective zero-point energy. The agreement with experimental data resembles
the results obtained for spontaneous fission half-lives, indicating the
capability of BCPM to consistently describe a large variety of fission
phenomena, including cluster emission.
