The Walecka model is studied at finite temperatures in one, two, and three spatial dimensions. The critical temperatures (T{sub c}) and densities ({rho}{sub c}) for the liquid-gas phase transition are calculated in these dimensions. As expected from a mean-field approach, the phase diagram in the T/T{sub c} versus {rho}/{rho}{sub c} plane is dimension independent in the vicinity of the critical point. An interesting finding is that, because the critical and ''flash'' temperatures are proportional, within numerical errors, dimension-independent curves can also be obtained for the incompressibility by scaling with the ''flash'' point coordinates (T{sub f},{rho}{sub f}). At the high-temperature regime, only the two- and three-dimensional systems present a phase transition. (c) 2000 The American Physical Society.
