Angular distributions from the ($d, p$) reactions on ${\mathrm{Zn}}^{64,66,68,70}$ have been measured with 10.0-MeV deuterons from the Argonne Tandem van de Graaff accelerator. The energies, spins, parities, and spectroscopic factors of levels up to about 3.5-MeV excitation energy have been determined by use of distorted-wave Born-approximation calculations. Empirical $J$-dependence rules are used to distinguish between ${\frac{3}{2}}^{-}$ and ${\mathrm{½}}^{-}$ states. The ground-state $Q$ values of the ${\mathrm{Zn}}^{64,66,68,70}(d, p)$ reactions, determined within ±10 keV, were 5.758, 4.827, 4.259, and 3.609 MeV, respectively. The sums of the spectroscopic factors are discussed briefly.
