Query: Investigation of $^{4}He_{3}$ trimer on the base of Faddeev equations in
  configuration space   Precise numerical calculations of bound states of a three-atomic Helium
cluster are performed. The modern techniques of solution of Faddeev equations
are combined to obtain an efficient numerical scheme. Binding energies and
other observables for ground and excited states are calculated. Geometric
properties of the clusters are discussed.
