Isotopic and isotonic chains of superheavy nuclei are analyzed to search for spherical double shell closures beyond Z=82 and N=126 within the new effective field theory model of Furnstahl, Serot, and Tang for the relativistic nuclear many-body problem. We take into account several indicators to identify the occurrence of possible shell closures, such as two-nucleon separation energies, two-nucl...

Recently, nuclear structure in neutron-rich nuclei has attracted much attention because of its exotic nature, such as halo and skin 1) 3). Recent advances of secondary beam techniques allow us to measure useful structure information on masses, interaction cross sections and excited states. The shell structure is one of essential issues in nuclear structure. Recently, the magic numbers in the ne...

The paper reviews the recent progress in description of isospin-symmetry breaking within nuclear shell model and applications to actual problems related structure decay exotic neutron-deficient nuclei along N=Z line, where N is neutron number Z atomic number. review recalls fundamentals isospin formalism for two-nucleon many-nucleon systems, including quantum numbers, spectrum’s selection rules...
