  One-particle spectral properties in the normal phase of the two-dimensional
attractive Hubbard model are investigated in the weak coupling regime using the
non-selfconsistent T-matrix approximation. The corresponding equations are
evaluated numerically directly on the real frequency axis. For temperatures
sufficiently close to the superconducting transition temperature a pseudogap in
the one-particle spectral function is observed, which can be assigned to the
increasing importance of pair fluctuations.
