"During the last several decades, the study of nuclear shapes has been of prime importance. A large number of investigations, both theoretical and experimental, have led to the discovery of a rich variety of nuclear shapes like, the basic spherical, deformed, superdeformed, triaxial, shape coexistence, reflection asymmetric (pear-shape) and other exotic ones. Apart from common nuclear structural properties, each of the mentioned shapes manifests properties associated with its specific form. It is interesting to note that most deformed nuclei are prolate deformed. In this monograph, attention is paid to pear-shaped nuclei"--
