3- and 4- body meson- nuclear clusters

The binding energies and matter distributions for the 3- body systems like $\varphi$- meson + 2N, 2$\varphi$ + N and 4- body system like $\varphi$+3n are calculated. For the 3- particle systems two- dimensional Faddeev equations in the differential form are used. For the 4- body system $\varphi$+3n the folding model is applied.
