We discuss specific features of those angular correlation experiments sensitive to the nuclear polarization in the intermediate state and investigate, in view of radiation damage studies, the interest of using allowed as well as first-forbidden β-decay as the primary radiation in a TDPAC cascade. The description of the technique is illustrated by experiments on the samples {Mathematical expression} and {Mathematical expression} produced by ion implantation into nickel single crystals. These results clearly demonstrate the unique possibility to make the experiments selectively sensitive to those impurity atoms associated with lattice defects. Although the formulation is in all aspects general especially the cross terms (k1≠k2) in the angular correlation treatment are emphasized. In this way the presence of a combined hyperfine interaction, cumbersome for radiation damage studies, has been explored to gain sensitivity in impurity site characterization.
