Query: Binding of eta_c meson with light nucleus   Binding energy of eta_c with ^4 He has been calculated on the basis of Yukawa
type potential. Final Rank Approximation (FRA) has been used for microscopical
treatment of the initial 5-body problem. The results are compared with the
results of the folding model and variational calculations.
