Appearance of Magic Numbers in the Unified Approach for the Nuclear Structure

Authors: Ranjeet Dalal

Taking the clues from the recently observed phenomena like correlated neutron-proton ejection from nuclei by energetic e-/protons, EMC effect and inconsistent assumptions of liquid drop and shell models for the same set of nuclei (for explanation of different nuclear properties), a unified approach for the nuclear structure was suggested by the author [1]. In the proposed approach, instead of freely moving individual neutrons/protons, nucleons exist in the form of tightly bound np and npn (and pnp also for proton rich nuclei) quasi-particles, which move in overall Coulomb well due to all other quasi-particles. The proposed approach was found to be very useful in understanding many unexplained phenomena [1]. Now, the existence of np and npn quasi-particles is found to be strongly confirmed by the presence of magic numbers across the periodic table where many stable nuclei with different atomic number are found to be have same number of np and npn. For example, there are 30 different stable (or most stable isotope of nuclei with no stable isotope) nuclei with different Z having the magic number of 38 np, 20 nuclei with the magic number of 32 np and 16 with magic number of 40 np.
