Abstract :
We present a mathematically rigorous method for solving three-atomic bound state and scattering problems. The method is well suited for applications in systems where the interatomic interaction is of a hard-core nature. It has been employed to obtain the ground- and excited-state energies for the helium trimer and to calculate the scattering phase shifts and wavefunctions for the He atom-He dimer at ultra-low energies.
