A simple line element for the dilaton gravity

The metric for the two-dimensional dilaton gravity can be written in an alt ernative form, similar to the two-dimensional Schwarzschild metric, and all ow us the identification of some quantities with those equivalent in the Sc hwarzschild solution. This new form, however, presents a nonphysical singul arity at the horizon in the same way that in the realistic four dimensional case. We show a procedure to eliminate this horizon singularity and, as an application, the resulting metric is used to obtain the associated Hawking temperature. We discuss also some differents between this metric and the S chwarzschild one.
