A one parameter solvable model for three bosons subject to delta functioninteractions in one-dimension with periodic boundary conditions is studied. Theenergy levels and wave functions are classified and given explicitly in termsof three momenta. In particular, eigenstates and eigenvalues are described asfunctions of the model parameter, c. Some of the states are given in terms ofcomplex momenta and represent dimer or trimer configurations for large negativec. The asymptotic behaviour for small and large values of the parameter, and atthresholds between real and complex momenta is provided. The properties of thepotential energy are also discussed.Comment: Revtex, 17 pages, 9 ps figures, to appear in Phys. Rev.
