| dc.description | The structure of collective bands in <sup>74,76</sup>Kr is studied within the framework of the deformed configuration mixing shell model based on Hartree-Fock states. The active single-particle orbits are 1p<sub>3/2</sub>, 0f<sub>5/2</sub>, 1p<sub>1/2</sub> and 0g<sub>9/2</sub> with <sup>56</sup>Ni as the inert core. A modified Kuo interaction has been used for the above configuration space. The <sup>74</sup>Kr nucleus is found to be the most deformed nucleus among the krypton isotopes which is in agreement with experiment. The deformation is found to decrease for the <sup>76</sup>Kr isotope. The calculated positive- and negative-parity bands agree quite well with the experiment for both the nuclei. A number of excited bands is also predicted. We have also calculated B(E2) values and compared them with available experimental data. The structure of the strongly coupled band built on K = 4<sup>( + )</sup> in <sup>76</sup>Kr is also studied. |
