  The MeV region of antineutrino energy is of special interest for physics
research and for monitoring nuclear nonproliferation. Whereas liquid
scintillation detectors are typically used to detect the Inverse Beta Decay
(IBD), it has recently been proposed to detect it with a liquid-organic Time
Projection Chamber, which could allow a full reconstruction of the particle
tracks of the IBD final state. We present the first comprehensive
simulation-based study of the expected signatures. Their unequivocal signature
could enable a background-minimized detection of electron antineutrinos using
information on energy, location and direction of all final state particles. We
show that the positron track reflects the antineutrino's vertex. It can also be
used to determine the initial neutrino energy. In addition, we investigate the
possibility to reconstruct the antineutrino direction on an event-by-event
basis by the energy deposition of the neutron-induced proton recoils. Our
simulations indicate that this could be a promising approach which should be
further studied through experiments with a detector prototype.
