Study Interacting Boson Model Calculations for (_62^154)Sm Nuclei

Abstract
In this research, (_62^154)Sm had been studied by using the interaction of Boson Model (IBM-1),to determine the low energy levels.(IBMT) program also used to evaluate the reduced transition probability B(E_2). Spin and parity had been determined for some energy levels, which were experimentally not exactly determined. We found that the spin and parity of ( 2_(3 ,)^+ 4_(3 )^+ and 6_(2 ,)^+) with energy levels (1.5400,1.3714 and 1.6606) MeV respectively. Also, we found that the (_^154)Sm isotopes belong to rotational of limits SU(3). Index terms- Energy levels, Nuclear structure, interacting boson model and (_62^154)Sm.
