Accepted: 8 July 2002
Three solutions of the Brans-Dicke theory with a self-interacting quartic potential and perfect fluid distribution are presented for a spatially flat FRW geometry. The physical behavior is consistent with the recent cosmological scenario favored by supernova type-Ia observations, indicating an accelerated expansion of the Universe.
