  This work is a pioneering study of backward-angle omega cross sections
through the exclusive 1H(e,e'p)omega reaction using the missing mass
reconstruction technique. The extracted cross sections are separated into the
transverse (T), longitudinal (L), and LT, TT interference terms. The analyzed
data were part of experiment E01-004 (Fpi-2), which used 2.6-5.2GeV electron
beams and HMS+SOS spectrometers in Jefferson Lab Hall C. The primary objective
was to detect coincidence pion in the forward-angle, where the backward-angle
omega events were fortuitously detected. The experiment has central Q2 values
of 1.60 and 2.45GeV2, at W=2.21GeV. There was significant coverage in phi and
epsilon, which allowed separation of sigma_T,L,LT,TT. The data set has a unique
u coverage of -u~0, which corresponds to -t>4GeV2.
  The separated sigma_T result suggest a flat ~1/Q^(1.33+/-1.21) dependence,
whereas sigma_L seems to hold a stronger 1/Q^(9.43+/-6.28) dependence. The
sigma_L/sigma_T ratio indicate sigma_T dominance at Q2=2.45 GeV2 at the ~90%
confidence level. After translating the results into the -t space of the
published CLAS data, our data show evidence of a backward-angle omega
electroproduction peak at both Q2 settings. Previously, this phenomenon showing
both forward and backward-angle peaks was only observed in the meson
photoproduction data. Through comparison of our sigma_T data with the
prediction of the Transition Distribution Amplitude (TDA) model, and signs of
sigma_T dominance, promising indications of the applicability of the TDA
factorization are demonstrated at a much lower Q2 value than its preferred
range of Q2>10GeV2. These studies have opened a new means to study the
transition of the nucleon wavefunction through backward-angle experimental
observables.
