Excitation energies, electromagnetic transition strength, and static moments in108,110,112,114,116CD nuclei are studied in the proton-neutron interacting boson model-2 (IBM-2). The calculations were carried out by using an improved version of the NPBOS code. The calculated values for Cd isotopes and the experimental ones agree. For the excitation energies the splitting of the 2-phonon multiplet was found rather small. In order to locate the Cd nuclei on the map of the IBM-2 parameters, the branching ratios were examined. It is found that Cd nuclei are classified in the U(5) limit.
