A Unified Approach for Nuclear Structure

Authors: Ranjeet Dalal

The nuclear physics area is plagued by variety of sophisticated models based upon initial ideas of liquid drop model or independent particle shell model. One set of models are used to understand binding energy and fission mechanism while the others are used to understand the nuclear shell structure and its implications. Further, some of the basic assumptions required for these models are apparently contradictory to each other. These models have their limited application area and can be used to account certain nuclear properties only. In present work, an unified approach for nuclear structure is proposed which can account the nuclear binding energy along with the nuclear shell structure for all ranges of nuclei. This model is based upon recent observations and do not use arbitrary assumptions like spin-orbit coupling term. It can be used to calculate various nuclear properties like binding energy, nuclear magnetic moments, quadrupole moments, similar excitation levels for mirror nuclei, emergence of new magic numbers for neutron rich nuclei or correlated two proton/neutron emission. Interestingly, it provides an straightforward explanation for asymmetric/symmetric fission fragment distribution in spontaneous/lowenergy fission events for heavy nuclei. Although, the proposed model is supported by many experimental evidences, further suggestions are given for verification of the approach.
