In our calculations the inter-atomic s-wave scattering length of the trapped bosons is suddenly increased to a very large value and the real-time evolution of the system is studied. Prompted by the very recent experimental data of $^{85}$Rb atoms at unitarity [Nature Phys. 10, 116 (2014)] we focus on the momentum distribution as a function of time.
