  Scattering of matter waves through slits has been explored using the Feynman
Path Integral formalism. We explicitly plot the near-zero probability densities
to analyse the behaviour near the slit. Upon doing so, intriguing patterns
emerge, most notably the braid-like structure in the case of double slits,
whose complexity increases as one increases the number of slits. Furthermore,
the plot shows the existence of a transition region, where the distribution of
near-zero probability points changes from the braided to the fringe-like
structure, which has been analysed by explicitly expressing the wavefunction as
a hypergeometric function. These patterns are analysed while considering the
continuity equation and its consequences for the regions with zero probability
density. As a result, we find quasi-traps in the region whose size can be
controlled and made much smaller than the wavelength of matter waves.
