  Beta-delayed neutron emission and $\beta$-delayed fission ($\beta$df)
probabilities were calculated for heavy, neutron-rich nuclei using the Los
Alamos coupled Quasi-Particle Random Phase Approximation plus Hauser-Feshbach
(QRPA+HF) approach. In this model, the compound nucleus is initially populated
by $\beta$-decay and is followed through subsequent statistical decays taking
into account competition between neutrons, $\gamma$-rays and fission. The
primary output of these calculations includes branching ratios along with
neutron and $\gamma$-ray spectra. We find a relatively large region of heavy
nuclides where the probability of $\beta$df is near 100%. For a subset of
nuclei near the neutron dripline, delayed neutron emission and the probability
to fission are both large which leads to the possibility of multi-chance
$\beta$df (mc-$\beta$df). We comment on prospective neutron-rich nuclei that
could be probed by future experimental campaigns and provide a full table of
branching ratios in ASCII format in the supplemental material for use in
various applications.
