${}_{}{}^{93}{}_{}{}^{}\mathrm{Tc}$ (2.8 h), ${}_{}{}^{94}{}_{}{}^{}\mathrm{Tc}$ (5 h), ${}_{}{}^{95}{}_{}{}^{}\mathrm{Tc}$ (20 h), ${}_{}{}^{93}{}_{}{}^{}\mathrm{Mo}_{}^m{}_{}{}^{}$ (7 h), ${}_{}{}^{109}{}_{}{}^{}\mathrm{In}$ (4.2 h), ${}_{}{}^{110}{}_{}{}^{}\mathrm{In}_{}^m{}_{}{}^{}$ (5 h), and ${}_{}{}^{111}{}_{}{}^{}\mathrm{In}$ (2.8 day) radioactive nuclei implanted by recoil into iron foils have been oriented at low temperature in a ${}_{}{}^3{}_{}{}^{}\mathrm{He}$-${}_{}{}^4{}_{}{}^{}\mathrm{He}$ dilution refrigerator. The following values have been established: $\left|\mu \right({}_{}{}^{93}{}_{}{}^{}\mathrm{Tc}_{}^g{}_{}{}^{}\left)\right|=\left[6.2\right(\{+11\mathrm{}\}\{-4\mathrm{}\}\left)\right]{\mu }_N$, $I\left({}_{}{}^{94}{}_{}{}^{}\mathrm{Tc}_{}^g{}_{}{}^{}\right)=7\mathrm{}$, $\left|\mu \right({}_{}{}^{94}{}_{}{}^{}\mathrm{Tc}_{}^g{}_{}{}^{}\left)\right|=\left[5.03\right(30\mathrm{}\left)\right]{\mu }_N$, $\left|\mu \right({}_{}{}^{110}{}_{}{}^{}\mathrm{In}_{}^m{}_{}{}^{}\left)\right|=\left[4.64\right(35\mathrm{}\left)\right]{\mu }_N$, $I^{\pi }({}_{}{}^{93}{}_{}{}^{}\mathrm{Mo}, 1520 \mathrm{keV})=\frac{7}{2^{+}}$, $\delta (\frac{E2\mathrm{}}{M1)}$ in ${}_{}{}^{93}{}_{}{}^{}\mathrm{Mo}$: $\delta (1363\mathrm{} \mathrm{keV}; \frac{7}{2}\to \frac{5}{2})=0.48\left(\{-8\mathrm{}\}\{+6\mathrm{}\}\right)$, $0.7\le \delta (1520\mathrm{} \mathrm{kev}; \frac{7}{2}\to \frac{5}{2})\le 1.9$; in ${}_{}{}^{94}{}_{}{}^{}\mathrm{Mo}$: $\delta (449\mathrm{} \mathrm{keV}; 6^{+}\to 6^{+})=0.0\left(\{+2\mathrm{}\}\{-1\mathrm{}\}\right) or 0.7\left(2\right)\mathrm{}$, $\delta (916\mathrm{} \mathrm{keV}; 6^{+}\to 6^{+})=-0.07\left(\{+7\mathrm{}\}\{-5\mathrm{}\}\right) or 0.8\left(1\right)\mathrm{}$; in ${}_{}{}^{95}{}_{}{}^{}\mathrm{Mo}$: $\delta (765\mathrm{} \mathrm{keV}; \frac{7}{2^{+}}\to \frac{5}{2^{+}})=0.11\mathrm{}\left(12\right)\mathrm{}$; in ${}_{}{}^{109}{}_{}{}^{}\mathrm{Cd}$: $\delta (205\mathrm{} \mathrm{keV}; \frac{7}{2^{+}}\to \frac{5}{2^{+}})=-0.13\mathrm{}\left(4\right)\mathrm{}$; in ${}_{}{}^{110}{}_{}{}^{}\mathrm{Cd}$: $\delta (\frac{M2\mathrm{}}{E1\mathrm{}}; 997 \mathrm{keV}; 5^{-}\to 4^{+})=-0.025\left(\{+35\mathrm{}\}\{-75\mathrm{}\}\right)$. Measured moments are compared with $j^n$ coupling predictions. Intermediate state reorientation due to randomly oriented quadrupole interaction has been observed for the 247 keV state of ${}_{}{}^{111}{}_{}{}^{}\mathrm{Cd}$.
