Hyperspherical harmonics with arbitrary arguments
A. V. Meremianin
The derivation scheme for hyperspherical harmonics (HSH) with arbitrary arguments is proposed. It is demonstrated that HSH can be presented as the product of HSH corresponding to s…

Collective multipole expansions and the perturbation theory in the quantum three-body problem
A. V. Meremianin
The perturbation theory with respect to the potential energy of three particles is considered. The first-order correction to the continuum wave function of three free particles is…
