We argue that the Anderson and Kondo models turn out to be irrelevant for the description of some strongly
correlated electron systems and suggest the mechanism for the formation of many-body states (heavy fermions)
being an alternative to the Kondo one. This mechanism involves the quantum tunneling of a heavy particle between
the states in the double-well potential.
