Abstract
The low lying nuclear structure of even (120,122,124,126,128,130) Te isotopes has been studied under the frame work of interacting boson model (IBM-1). The boson numbers are found 8, 7, 6, 5, 4, and 3 for Te-120,Te-122,Te-124 426,Te-128,Te-130 isotopes respectively. The ratio of the excitation energies of first 4(+) and first 2(+) excited states, R-4/2, has been also calculated for those nuclei. All calculated values are compared with the available experimental data and show reasonable agreement. It is found that even Te-120...130 isotopes have been considered to the U(5) symmetry.
