Abstract：
The level structure of ^76—84Kr isotopes is discussed within the framework of Interacting Boson Model (IBM-2). One-phonon mixed symmetry states J+2+ and two-phonon mixed symmetry states J +1+,2+ and 3+ have been identified by analyzing the wave function and M1 transitions. Special attention is paid to the occurrence of 0+2 which is not reproduced well by other calculations. The study of the influence of the [d+d] Lπ·[d+d] Lυ interactions on the nuclear structure of these nuclei are undertaken. The calculated results are compared with available experimental data; the results are in general good agreement.
