Abstract：
In view of the proton boson and neutron boson coupling, all possible dynamical symmetries in the proton-neutron interacting boson model (IBM2) are discussed. The symmetries are found to be in four types, of which some are newly discovered. The commonly used IBM2 computer code NPBOS is checked through the group-chain method. It shows that most results of the NPBOS calculations are correct except the case in which O_x·O_x and O_v·O_v are included in the Hamiltonian. Using a modified NPBOS,the energy levels and E2 transitions of ¹⁵⁰Sm and ¹⁵²Sm are studied.
