\begin{table}  %t4
\caption{\label{tab4}Magnetic dipole transition rates (in s$^{-1}$) for levels
within 3d$^7$ ground state configuration of \nifour. The table shows results
computed with neither TEC nor 2-body relativistic operators (w/o T + w/o 2-body), with 2-body
 relativistic operators (w/o T + 2-body), with TECs and 2-body relativistic operators (T + 2-body)
and with TECs, LEVs and  2-body relativistic operators (T + L + 2-body). The rates previously
reported by Hansen et~al. (\cite{Hansen1984}) and Garstang (1969) are also given.}
