Abstract
A mechanism of appearance and disappearance of the Efimov levels of the hel ium He-4(3) trimer is studied in the case where the force of interatomic in teraction varies. The resonances (including virtual levels) are calculated by means of solving a boundary value problem for the Faddeev differential e quations describing the (2 + 1 -> 2 + 1; 1 + 1 + 1) scattering processes.
