  We study the effect of finite time resolution on coherent superpositions of
rotating clockwise and anticlockwise wave packets in the regime of strongly
overlapping resonances of the intermediate complex. Such highly excited
deformed complexes may be created in binary collisions of heavy-ions, molecules
and atomic clusters. It is shown that time averaging reduces the interference
fringes acting effectively as dephasing. We propose a simple estimate of the
``critical'' time averaging interval. For the time averaging intervals bigger
than the critical one the interference fringes wash out appreciably. This is
confirmed numerically. We evaluate minimal energy intervals for measurements of
the excitation functions needed to observe the Schr\"{o}dinger Cat States.
These should be easily observable in heavy-ion scattering. Such an experiment
is suggested.
