Calculation The Energy Levels and Energy Bands(g, β, γ-bands) for Gd(A=140-160) Isotopes

Abstract

In the present work the interacting boson model version one have been used to calculate the energy levels and energy bands (g, β, γ-bands) of Gadolinium Gd(A=140-160) isotopes by using the program (IBSS1.for).This program calculate the eigen values and eigen vectors. The results were compared with the experimental data and they were found in a good agreement.
