摘要：

Within the framework of the interacting boson model-1, the energy levels and electromagnetic transitions in Kr72-84 isotopes are calculated. The structures of the eigenstate and Hamiltonian matrix for some low-lying states are also calculated. The calculated results are compared with available experimental data, and the results are generally in good agreement. The present study shows that the Kr-72,Kr-74,Kr-76,Kr-80,Kr-82,Kr-84 isotopes are in the transition from U(5) -> SU(3), and Kr-78 is in the transition from U(5) -> O(6).
