Structure of Atomic Helium Trimers
The structure of the bound states of the atomic helium trimers is calculated by use of hyperspherical coordinates and an adiabatic expansion of the Faddeev equations. The ground state of 4He3 has a triangular shape, the excited state is an Efimov state and the 3He4He2 bound state is a halo state.
