| Abstract: | Conditions are considered under which the ground-state wavefunctions of quantum systems of interacting particles in an external field are factorizable and can be found explicitly. The corresponding classical systems of particles are completely integrable; in the quantum case an extra integral of motion is constructed for a two-particle system. |
