Rotational States of the Helium Trimer in the Symmetry-Adapted Hyperradial-Adiabatic Approach
We have searched for bound rotationally excited states of the helium trimer using the symmetry-adapted hyperradial adiabatic approach. Since the calculated J p = 2+ and J p = 1− potential curves are both completely repulsive, we infer that there are no bound rotational states of 4He3. A recent adiabatic calculation  based on the direct solution of the Coriolis-coupled Schrödinger equation agrees with this conclusion.
