Abstract:The even-even Selenium isotopes in the A ∼80 mass region and the general features of its structure have been investigated within the framework of the interacting boson model-2. The neutron proton version of the model has been applied to the Se (A = 74 to 80) isotopes with emphasis on the description of the 0 + 1 , 2 + 1 , 0 + 2 , 2 + 2 and 4 + 1 states. The energy levels, B(E2) and B(M1) electromagnetic transition probabilities were calculated. The results of these calculations were compared with previous experimental results and were shown to be in good agreement.
