Low spin states in the odd-odd nucleus ${}^{50}\mathrm{Mn}$ were populated in the ${}^{50}\mathrm{Cr}(p,n\gamma {)}^{50}\mathrm{Mn}$ fusion evaporation reaction at 15 MeV beam energy at the FN-Tandem accelerator in Cologne. γ-angular correlations, $\gamma \gamma$ coincidences, and Compton asymmetries were measured. 21 states of ${}^{50}\mathrm{Mn}$ were observed, 16 for the first time. Six new spin assignments and two parity assignments were made. Eight multipole-mixing ratios and nine new γ-decay branching ratios were determined for the first time. A full pf-shell model calculation for the low-lying states in ${}^{50}\mathrm{Mn}$ is compared to the data.
