High spin states in ${}_{}{}^{62}{}_{}{}^{}\mathrm{Zn}$ have been observed using the ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$(${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$, $\alpha 2p\gamma$)${}_{}{}^{62}{}_{}{}^{}\mathrm{Zn}$ reaction at beam energies of 93.5 and 102 MeV. $\gamma -\gamma$ coincidence measurements, angular distributions, and directional correlation of oriented nuclei ratios were used to determine a likely decay scheme. Levels with probable spin as high as $J=12\mathrm{}$ have been observed.

NUCLEAR REACTIONS ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$(${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$, $\alpha 2p\gamma$) 93.5 and 102 MeV: measured $E_{\gamma }$, $\sigma (E_{\gamma },\theta )$, $\gamma -\gamma$ coincidence. ${}_{}{}^{62}{}_{}{}^{}\mathrm{Zn}$ deduced $E_x$, $J$, $\pi$ decay scheme.
