ResumoPion double charge exchange has been used to populate the double isobaric analog state (DIAS) in $^{208}\mathrm{Po}$ with use of the doubly magic target $^{208}\mathrm{Pb}$. The DIAS was found at an excitation energy of 32.46\ifmmode\pm\else\textpm\fi{}0.17 MeV with a width of 0.85\ifmmode\pm\else\textpm\fi{}0.40 MeV. The excitation energy of the DIAS can be used along with the energy of the isobaric analog state to determine separately the linear and the quadratic terms of the isobaric multiplet mass equation. The resulting linear and quadratic terms are b=-31.6\ifmmode\pm\else\textpm\fi{}3.7 MeV and c=0.33\ifmmode\pm\else\textpm\fi{}0.09 MeV, respectively.
