  We report calculations of energy levels and radiative rates ($A$-values) for
transitions in Cr-like Co IV and Ni V. The quasi-relativistic Hartree-Fock
(QRHF) code is adopted for calculating the data although GRASP (general-purpose
relativistic atomic structure package) and flexible atomic code (FAC) have also
been employed for comparison purposes. No radiative rates are available in the
literature to compare with our results, but our calculated energies are in
close agreement with those compiled by NIST for a majority of the levels.
However, there are discrepancies for a few levels of up to 3\%. The $A$-values
are listed for all significantly contributing E1, E2 and M1 transitions, and
the corresponding lifetimes reported, although unfortunately no previous
theoretical or experimental results exist to compare with our data.
