The Eckart frame Hamiltonians in the three-body problem
arXiv:1211.3947 · doi:10.1007/s10910-013-0152-9
Abstract
The Eckart frame is used to separate out the collective rotations in the quantum three-body problem. Explicit expressions for the corresponding rotational and vibro-rotational (i.e. Coriolis) Hamiltonians are derived. Special attention is paid to the situation when two principal moments of inertia are equal in the equilibrium configuration.
