Band structure of low lying bands of some neutron rich odd-odd Eu isotopes

The odd odd Eu isotopes in the mass region A=150-160 provide an interesting possibility to study the low lying rotational band structure of these isotopes. The experimental data available on properties and characteristics of band levels of these doubly odd Eu isotopes in the mass region (A=150-160) pose a challenge to theorists to reproduce the extremely complex band spectra of these nuclei. It should be noted that from the neutron number N=89, these isotopes show emergence of deformation and rotational band spectra. In this work, an attempt has been made to study the low spin complex spectroscopy of these nuclei to understand the structure of yrast band and the low lying excited bands in these isotopes
