We report on a Rosenbluth separation using previously published data by theCLAS collaboration in Hall B, Jefferson Lab for exclusive $\pi^{0}$ deeplyvirtual electroproduction (DVEP) from the proton at a mean $Q^{2}$ of $\approx$2 (GeV/c)$^{2}$. The central question we address is the applicability offactorization in $\pi^0$ DVEP at these kinematics. The results of ourRosenbluth separation clearly demonstrate the dominance of the longitudinalcontribution to the cross section. The extracted longitudinal and transversecontributions are in agreement with previous data from Hall A at Jefferson Lab,but over a much wider $-t$ range (0.12 - 1.8 (GeV/c)$^{2}$). The measureddominance of the longitudinal contribution at $Q^{2} \approx$ 2 (GeV/c)$^{2}$is consistent with the expectation of the handbag factorization theorem. Wefind that $\sigma_L(t) \sim 1/(-t)$ for $-t >$ 0.5 (GeV/c)$^2$. Determinationof both longitudinal and transverse contributions to the deeply virtual$\pi^{0}$ electroproduction cross section allows extraction of additional GPDs.
