The isovector giant monopole resonance (IVGMR) is a fundamental mode of collective oscillation in which the neutron and proton fluids in a nucleus radially expand and contract in an out-of-phase manner. Observation of the IVGMR has been difficult. The non-spin-transfer IVGMR resonance is obscured by its spin-transfer counterpart, the isovector spin giant monopole resonance (IVSGMR). The problem is the lack of a suitable probe for measurement of non-spin-transfer, isovector events. By way of the (\sups{10}Be,\sups{10}B$+\gamma$) charge-exchange reaction, selectivity for the excitation of the IVGMR can be gained. Isolation of \delJ{S}{0}, \delJ{T}{1} reactions is achieved through excitation of the superallowed Fermi transition \sups{10}Be(0\sups{+},g.s.)$\rightarrow$\sups{10}B(0$_{1}^{+}$, 1.74 MeV,\delJ{T}{1}), which is detected by observation of the 1022 keV gamma ray from the deexctation of the isobaric analogue state in \sups{10}B to the \sups{10}B(1$_{1}^{+}$, 0.718 MeV) state. The applicability of this probe in separation of \delJ{S}{0}, \delJ{T}{1} reactions is observed with data taken on a \sups{12}C target through selectivity in observation of the \sups{12}C(0\sups{+},g.s.)$\rightarrow$\sups{12}B(1\sups{+},g.s.) transition, which is \delJ{S}{1} by definition. IVGMR strength in \sups{28}Al is identified using the the \sups{28}Si(\sups{10}Be,\sups{10}B+$\gamma$) reaction at E(\sups{10}Be)=1000 MeV. Isovector monopole strength is observed up to E\subs{x}(\sups{28}Al)=30 MeV. The observed non-energy weighted sum rule strength for peaks at 9 and 21 MeV is determined to be $66\pm36$\% and $59\pm32$\%, respectively. Exctracted IVGMR and isovector giant dipole resonance distributions are also compared with results from calculations in the charge-exchange relativistic time blocking approximation.
