DESCRIPTION:We deal with a class of reaction-diffusion equations in space 
 dimension d > 1 perturbed by a Gaussian noise which is white in time and c
 olored in space. We assume that the noise has a small correlation radius d
 \, so that it converges to the white noise\, as d goes to zero.\nBy using 
 arguments of Gamma Convergence\, we prove that\, under suitable assumption
 s\, the quasi potential converges to the quasi-potential corresponding to 
 space-time white noise.\nWe apply these results to the asymptotic estimate
  of the mean of the exit time of the solution of the stochastic problem fr
 om a basin of attaction of an asymptotically stable point for the unpertur
 bed problem.\n
