The existence of super heavy elements is one of the major issues in nuclear physics. Many experimental and theoretical efforts have been made to study the super heavy elements during last decades. In order to achieve reliable predictions in the super heavy mass region, a good understanding of the properties of heavy mass nuclei is essential. In the present work, the B(E2) transition probabilities and g-factors of even-even Curium (Cm) isotopes have been studied by using projected shell model approach, which is a bridge connecting the shell model and meanfield approaches. The E2 transition probabilities and g-factors have been calculated by using the many body wave functions that reproduce the ground state bands of Cm isotopes. The calculated B(E2) values reproduces the available experimental data. The predicted values of B(E2)s, show an increasing trend with spin and the predicted values of g-factors show a slight variation at higher spins. The energy states of these nuclei at lower spin arise from almost pure quasiparticle configuration in which all the nucleons are paired. Therefore, g-factors of these nuclei with spin are not showing much variation. The predicted values of E2 transition probabilities are useful in understanding the properties of nuclear excitations and electromagnetic quantities of Cm isotopes needs experimental confirmation.

Abstract


The existence of super heavy elements is one of the major issues in nuclear physics. Many experimental and theoretical efforts have been made to study the super heavy elements during last decades. In order to achieve reliable predictions in the super heavy mass region, a good understanding of the properties of heavy mass nuclei is essential. In the present work, the B(E2) transition probabilities and g-factors of even-even Curium (Cm) isotopes have been studied by using projected shell model approach, which is a bridge connecting the shell model and meanfield approaches. The E2 transition probabilities and g-factors have been calculated by using the many body wave functions that reproduce the ground state bands of Cm isotopes. The calculated B(E2) values reproduces the available experimental data. The predicted values of B(E2)s, show an increasing trend with spin and the predicted values of g-factors show a slight variation at higher spins. The energy states of these nuclei at lower spin arise from almost pure quasiparticle configuration in which all the nucleons are paired. Therefore, g-factors of these nuclei with spin are not showing much variation. The predicted values of E2 transition probabilities are useful in understanding the properties of nuclear excitations and electromagnetic quantities of Cm isotopes needs experimental confirmation.
