We theoretically investigate the free dispersion,
scattering and disintegration
of an N-particle quantum soliton by Bragg light pulses,
comparing the exact quantum result
with its quasiclassical (mean-field) limit.
Remarkably, we find that the correlation properties of a
quantum soliton approach the (mean-field) limit very
rapidly as the particle number N grows.
A modest discrepancy between
the classical and quantum results is observed for 
.
