Abstract
Laser excitation is used to create small polyatomic ions with excitation in selected vibrational modes. These are formed into a beam and collided with a neutral target gas. Reactions are studied and product recoil energy distributions are measured as a function of collision energy and vibrational state. A wide variety of dynamical behavior is observed: strong mode-selective vibrational effects, severe steric bottlenecks, mode-dependent barrier crossing, complex lifetimes ranging from 10 microsecond(s) ec to 100 fsec, and impact parameter dependent mechanism switching.
