Abstract

It is shown that the set of transformations of the s and d boson operatorsthat maintain the IBM-like form of the Hamiltonian comprises a discrete point symmetry group D-2. ' The transformations manifest themselves as a parameter symmetry of the IBM-1 Hamiltonian. The transformations considered are also necessary for constructing the most general IBM-2 Hamiltonian. The properties of the potential energy surfaces arising in connection with these transformations are discussed. (C) 2000 MAIK "Nauka/lnterperiodica".
