New ISR Cross Section Results on $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0$ and $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}\eta$ from BaBar

Two new hadronic cross sections measured by the BaBar experiment are presented: $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0$ and $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}\eta$. For both channels, the contribution the anomalous magnetic moment of the muon is calculated.
