Low-spin states of ${}^{130}\mathrm{Xe}$ have been populated by a fusion evaporation reaction followed by $\beta$-decay ${}^{126}\mathrm{Te}({}_3^7\mathrm{Li},3n){}^{130}\mathrm{Cs}\stackrel{\mathrm{EC}}{\to }{}^{130}\mathrm{Xe}$. Two candidates for $2_{1,\mathrm{ms}}^{+}$-states could be found, by measuring the $E2/M1$ mixing ratio of the transitions of the $2_3^{+}$ and $2_4^{+}$, at 2150 keV and 2296 keV, to the first excited $2^{+}$ state. The experimental results are supported by a shell model calculation and are in a good agreement with interacting boson model-2 (IBM-2) calculations. The mixing of the $2_{1,\mathrm{ms}}^{+}$ with a symmetric $2^{+}$-state and its fragmentation into the $2_3^{+}$ and $2_4^{+}$ states are discussed.
