Abstract
The property of (134-140)Neodymium nuclei have been studied in framework Interacting Boson Model (IBM) and a new method called New Empirical Formula (NEF). The energy positive parity bands of Nd134-140 have been calculated using (IBM) and (NEF) while the negative parity bands of Nd134-140 have been calculated using (NEF) only. The E-GOS curve (E gamma/I) as a function of the spin (I) has been drawn to determine the property of the positive parity yrast band. The parameters of the best fit to the measured data are determined. The reduced transition probabilities B(E2) of these nuclei was calculated. The critical point has been determined for Nd-140 isotope. The potential energy surfaces (PESs) to the IBM Hamiltonian have been obtained using the intrinsic coherent state. (C) 2018 Elsevier B.V.
