Calculations for energy levels, radiative rates and lifetimes have beenperformed for three Ne-like ions, namely Hf~LXIII, Ta LXIV and Re LXVI, forwhich the general-purpose relativistic atomic structure package (GRASP) hasbeen adopted. Results are presented among the lowest 121 levels of these ions,which belong to the 2s$^2$2p$^6$, 2s$^2$2p$^5$3$\ell$, 2s2p$^6$3$\ell$,2s$^2$2p$^5$4$\ell$, 2s2p$^6$4$\ell$, and 2s$^2$2p$^5$5$\ell$ configurations,but CI (configuration interaction) has been considered among a much largernumber of levels. No measurements for energy levels are available butcomparisons have been made with the earlier similar theoretical results.Additionally, calculations have also been performed with the flexible atomiccode (FAC) in order to assess the effect of (much) larger CI on energy levels.
