The energies of the ηc - d and ηc-3He bound states are calculated by using genuine three- and four-body scattering equations. For the NN interaction the separable version of the Paris potential is used. For the ηc N interaction we adopted a local Yukawa-type potential which is expanded into a series of separable potentials by means of the unitary pole approximation method. The results are compared with earlier calculations.
