Özet
The 134Ba isotope (Z = 56) lies in the transitional region closer to the vibrational range of nuclei. Energy levels B(E2), B(M1) and the mixing ratios d (E2/M1) and X(E0/E2) for selected transitions were calculated in the framework of the proton-neutron interacting boson model (IBM-2). All results were compared with experimental data. Some experimental X(E0/E2) ratios were calculated from available experimental data. Majorana parameters were found to have a great effect on the calculated energy levels of the 23+ and 24+, which indicate that both of them have mixed symmetry properties.
