Abstract
A In this study, the ground state band (GSB), , and γ bands of even- even isotopes were calculated using the interacting boson model (IBM-1), the Semi-Empirical Formula (SEF), and the new empirical equation (NEE). The initial step in determining the properties of the nuclei was to calculate the ratio between the second and first excited states ⁄ ⁄ . The corresponding coefficients for the IBM-1 model of rotational SU(3) were also determined. In addition, the corresponding coefficients of the two equations SEF and NEE were calculated through the fitting process of the ground state band and and γ bands. The energy state bands for the three methods (IBM-1, SEF, and NEE) were compared with the available experimental values, and the NEE method was found to be the most compatible with the experimental data. The IBM-1 derived electric quadrupole transition probabilities B(E2) were calculated for the isotopes studied and found to agree well with the available experimental data. The potential energy surface (PES) of the isotopes was then computed on the basis of its importance in determining the final shape of the nucleus. Using two significant parameters of the potential energy surface, namely the parameter of the total distortion of the nucleus and the deviation from axial symmetry, PES concludes that these nuclei possess rotational properties. --- page 102 [OCR+] --- Study of the Properties of some Even-Even 162-172Er Isotopes A Thesis Submitted By Amal Mahdi Saleh Al Nuaimi To The Council of College of Education for Pure Science University of Mosul in Partial Fulfillment of Requirements for The Degree of M.Sc.
