Query: Exclusive $\pi^{-}$ Electroproduction off the Neutron in Deuterium in
  the Resonance Region   New results for the exclusive and quasi-free cross sections off neutrons
bound in deuterium ${\gamma}_vn(p) \rightarrow p{\pi}^{-} (p)$ are presented
over a wide final state hadron angle range with a kinematic coverage of the
invariant mass ($W$) up to 1.825 GeV and the virtual photon four-momentum
transfer squared ($Q^{2}$) from 0.4 to 1.0 GeV$^2$. The exclusive structure
functions have been extracted and their Legendre moments were obtained.
Final-state-interaction contributions have been kinematically separated from
the extracted quasi-free cross sections off bound neutrons solely based on the
analysis of the experimental data. These new results will serve as long-awaited
input for phenomenological analyses to extract the $Q^{2}$ evolution of
previously unavailable $n \to N^{*}$ electroexcitation amplitudes and to
improve state-of-the-art models of neutrino scattering off nuclei by augmenting
the already available results from free protons.
