    "abstract": "Using an angular momentum projected single particle basis, a pnQRPA approach\nis used to study the $2\\nu\\beta\\beta$ properties of ten isotopes, exhibiting\nvarious quadrupole deformations. The mother and daughter nuclei exhibit\ndifferent quadrupole deformations. Since the projected basis enables a unified\ndescription of deformed and spherical nuclei, situations where the nuclei\ninvolved in the double beta decay process are both spherical, both deformed or\none spherical and another deformed, can be treated through a sole formalism.\nDependence of single $\\beta^-$ and $\\beta^+$ strength distribution on atomic\nmass number and nuclear deformation is analyzed. For the double beta decay\nprocess, the Gamow-Teller transition amplitudes and half lives are calculated.\nResults are compared with the experimental data as well as with the predictions\nof other theoretical approaches. The agreement between the present results and\nexperimental data is fairly good.",
