The linear baryon

We describe classical orbits and quantum states of a three-particle system, which is weakly chaotic. The quantum energies of the lowest 48 states, whi ch are invariant under permutations, are given both for various approximati ons and to high accuracy. The quantum mechanical probability distributions are given in a two-dimensional version of the system, the hexagonal pit. Th e quantum probabilities show strong resemblance to classical orbits of vari ous types, including chaotic ones.
