Though gravitational collapse is the key phase determining the evolution of prestellar cores into protostars, how it proceeds remains unclear, as detailed high-resolution studies are rare. Our previous N2H+(1-0) observations carried out with the IRAM 30 m and modelling of the emission have revealed extremely fast (v~200 m/s) infall motions in the prestellar core L1689B. Observations at high angular resolution are needed in order both to confirm unambiguously the presence of infall and characterise in detail the velocity field in the inner core, where the protostar will be born: we therefore propose to map L1689B in N2H+(1-0) with ATCA at a resolution of 7" and high spectral resolution. The modelling of the observations with our N2H+ radiative transfer code will yield small scale infall velocity profiles needed to discriminate between the different theories of gravitational collapse.
