The properties of the rare gas clusters of helium and neon are studied. The calculations of the bound state energies of helium and neon trimers are performed within Faddeev differential equation in total angular momentum representation.

Kolganova et al. (Few-Body Syst 51:249, 2011) reviewed the results that demonstrate the Efimov nature of the $$^4$$ He three-atom system. The present note represents an extension of that survey to the time period which passed since its publication.

Corrects schemes for solving equations of three-body dynamics for systems governed by a zerorange two-body interaction are considered. Correlations between spectral features of a three-boson system are obtained. The results are compared with the resu

The binding energies of the systems $${{\phi n n}}$$ , $${{\phi n p}}$$ , and $${{\phi p p}}$$ are calculated on the basis of Faddeev equations. The results indicate the possibility of new few-nucleon meson clusters.

We review results on scattering observables for $^4$He--$^4$He$_2$ and $^3$He--$^4$He$_2$ collisions. We also study the effect of varying the coupling constant of the atom-atom interaction on the scattering length.
