The even-even 76Se isotope in the A~80 mass region and the general features of its structures have been investigated within the framework of the interacting boson model-II. The neutron proton version (IBM-II) of this model has previously been applied successfully to the light 76Se isotope with emphasis on the description of the 0+1, 2+1, 0+2, 2+2 and 4+1 states. The energy levels were calculated by using the NPBOS program code including the Hamiltonian parameters. The electromagnetic transition probabilities, B(E2;2+1 -> 0+1), B(E2;0+2 -> 2+1), B(E2;4+1 -> 2+1) B(E2;2+2 -> 2+1), B(E2;2+2 -> 0+1) and B(M1;2+2 -> 2+1 ), were computed
by using the NPBTRN program code. Neutron-proton boson effective charges (eπ,ev) and g factors (gn,gv) were obtained by fitting to experimental values. The calculated energy levels and calculation of electromagnetic transition probabilities were compared with experimental and some previous theoretical results. It is seen that they are in good agreement.
