  Energies and lifetimes are reported for the lowest 375 levels of five Br-like
ions, namely Sr~IV, Y~V, Zr~VI, Nb~VII, and Mo~VIII, mostly belonging to the
4s$^2$4p$^5$, 4s$^2$4p$^4$4$\ell$, 4s4p$^6$, 4s$^2$4p$^4$5$\ell$,
4s$^2$4p$^3$4d$^2$, 4s4p$^5$4$\ell$, and 4s4p$^5$5$\ell$ configurations.
Extensive configuration interaction has been included and the general-purpose
relativistic atomic structure package ({\sc grasp}) has been adopted for the
calculations. Additionally, radiative rates are listed among these levels for
all E1, E2, M1, and M2 transitions. From a comparison with the measurements,
the majority of our energy levels are assessed to be accurate to better than
2\%, although discrepancies between theory and experiment for a few are up to
6\%. An accuracy assessment of the calculated radiative rates (and lifetimes)
is more difficult, because no prior results exist for these ions.
