In the present paper, mixed Abelian groups with isomorphic endomorphism semigroups are studied. In particular, we characterize the groups whose periodic parts are nonisomorphic, while their endomorphism semigroups are isomorphic. A description of nonreduced split mixed Abelian groups with $UA$-rings of endomorphisms is obtained.
Keywords: mixed Abelian group, endomorphism semigroup, $UA$-ring of endomorphisms.
