The stability of different phases of the three-dimensional nonrelativistic electron gas is analyzed using stochastic methods. With decreasing density, we observe a {ital continuous} transition from the paramagnetic to the ferromagnetic fluid, with an intermediate stability range (20{plus_minus}5{le}r{sub s}{le}40{plus_minus}5 ) for the {ital partially} spin-polarized liquid. The freezing transition into a ferromagnetic Wigner crystal occurs at r{sub s}=65{plus_minus}10 . We discuss the relative stability of different magnetic structures in the solid phase. {copyright} {ital 1999} {ital The American Physical Society}
