The present study was under taken to measure the uranium concentration in female teeth samples collected from different nationalities. The determination of uranium concentration in these samples has been done by using CR-39 track detector. The nuclear reaction is used as a source of nuclear fission fragments is (n,f) obtained by the bombardment of U-235 with thermal neutrons with flux (5x10 3 n/cm 2 .s) was used from ( Am-Be) neutron source. The concentration values were calculated by a comparison with standard samples which prepared. The obtained results show that the concentration is ranging from (0.58 0.7ppm) in Oman and Uae to (0.35 0.03ppm) in Iraqi for male, the uranium concentration was the highest in Oman and Uae for female.
The nuclear structure for even-even nuclei estimated by using interacting boson model (IBM-1). Also this program was used to determine energy levels of g- state, energy ratios and electric quadrupole transitions probability B(E2) which have been calculated. Depending on the follow up of energy ground bands (g, β, and γ) . The dynamical symmetry and energy spectrum of selected isotope are determined by B(E2). The electric quadrupole transition probability of the (2ᶢ+-0ᶢ+) transitions for Yb (A=164) isotopes with the dynamical symmetry SU(3)- SU(5) from rotational SU(3) to vibrational SU(5). All obtained results of the study were compared with experimental facts and acceptable agreement obtained.

The nuclear structures of even-even isotopes Nd (A=148,150,152) are studied by using the first
Interacting Boson Model (IBM-1). The energy levels of ground state, beta and gamma bands
,energy ratios are calculated. The results showed dynamical symmetry of these isotopes SU(3)-
SU(6), SU(5)-SU(6).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
