Abstract

The energy levels of low- lying bands have been calculated using the Interacting Boson Model (IBM-2), New Empirical Formula (NEF) and Bohr - Mottelson Model (BM), while the rest of the levels including the negative parity bands (NPS) of even-even Neodymium isotopes Nd (144-150) have been calculated using only  NEF and BM. The electrical transition probabilities  of Nd nuclei have also been calculated. A comparison between the results and the available experimental data illustrated a very good agreement. To determine the property of the ground-state band, the ratio  as function of the spin ( ) has been plotted.
