Query: Statistics of resonance and non-resonance tunnelling of fermionised cold
  atoms   We show that a short-range strong repulsive (contact) interaction between the
particles in the barrier may change the statistics of two-particle tunnelling.
In the case of a resonance of a width $\Gamma$, the effect would be observed if
the time between the two impacts is of order of $\hbar/\Gamma$. The statistics
of non-resonance tunnelling across a broad potential barrier remain unaffected,
which suggests that there is no appreciable delay in the classically forbidden
region.
