               "The decay of a NHIM to dust"


We study a prototypical 3-degrees-of-freedom chaotic scattering system 
depending on a perturbation parameter. For one limiting case the system 
has a conserved quantity and can be reduced to a 2-degrees-of-freedom 
system. For the other limiting case it is completely hyperbolic. For the 
reducible case the dynamics is directed by a NHIM and the 4D Poincaré 
map can be understood as a stack of reduced 2D maps. As the perturbation 
sets in, for small values of the perturbation parameter the NHIM 
persists, and for large perturbations it decays to dust.
