  We present a method to select events with specific initial configuration,
namely body-tip, in heavy-ion collisions using deformed Uranium nuclei. We
propose to use asymmetry in spectator neutron numbers to filter out these
body-tip events from the unbiased configurations in U+U collisions. We have
used a variable S_eta to differentiate between the body-tip and unbiased
configurations. We have calculated the second order azimuthal anisotropy,
namely elliptic flow (v2), for this body-tip configuration in the framework of
a transport model and found it to be consistently lower compared to that in
unbiased configurations as we expected. The purity of selecting such events in
a real experiment is also discussed.
