The ground state properties of the atomic nuclei provide valuable information on their structure. The investigation of atomic nuclei is one of the fundamental and mostly pursued topics of the natural sciences, owing to its direct as well as indirect impact on human life. Atomic nuclei being quantum many-body systems, render the investigation of their properties among the challenging disciplines of the natural sciences. It is because of the fact that the single particle and the collective behavior of the constituents is at play almost on the same scales, making them interesting laboratories for the investigation of the different phenomena. These phenomena are also responsible for the varied shapes of atomic nuclei i.e., spherical, prolate, oblate etc. These shape changes take place from spherical doubly-magic (closed shell) nuclei, as one moves away from the valley of stability towards the drip lines, one can find the diversity in shapes of atomic nuclei and hence variation in their size, resulting in the change in the rms radii. In the present work the Sr isotopes have been investigated using the microscopic Energy Density Functional approach. The HFBTHO solver has been employed for calculation of binding energies, charge radii and the two-neutron separation energies which are in agreement with the experimentally measured values.
