  A new Langevin equation with a field-dependent kernel is proposed to deal
with bottomless systems within the framework of the stochastic quantization of
Parisi and Wu. The corresponding Fokker-Planck equation is shown to be a
diffusion-type equation and is solved analytically. An interesting connection
between the solution with the ordinary Feynman measure, which in this case is
not normalizable, is clarified.
