In this paper we present new results on stellar fundamental parameters for early B and Be field stars observed in the southern hemisphere: effective temperature, superficial gravity, and projected stellar rotation velocity. The estimation of their projected rotation velocities is made by two successive methods. We first obtain an initial value based on Fourier transforms of the He I λ4471 line for 34 B and Be field stars with magnitudes in the range 0.5≤m_v≤10, followed by a more accurate fitting procedure of observed lines with non-LTE model line profiles. This procedure yields stellar rotation velocity estimates that are in agreement with those of the literature. We derive also T_effand logg values by fitting equivalent widths and profiles of NLTE model spectra to the observed ones. Finally, we give estimates of stellar ages, masses, and bolometric luminosities derived from interpolations in the evolutionary tracks calculated by Schaller.
