The growth of free silver nanoclusters is studied by molecular dynamics simulations, from a small seed up to sizes N similar or equal to 150. It is Shown that the final outcome of the growth process depends crucially on the growth conditions (deposition flux phi and temperature T). A reentrant morphology transition is obtained: at intermediate values of T and phi a decahedral window is found; the window is surrounded by regimes where icosahedra are preferentially grown.
