Abstract
Since Rutherford discovered the nucleus in 1910, the knowledge of the nucleus has grown significantly. The different models provide a basic understanding of the variety of phenomena observed in atomic nuclei which have not been explained under the framework of a single unifying model. This models are Liquid DROP models, the shell model that was developed by Mayer and Jensen and the collective model was developed by Bohr and Mottelson.The perfect application of dynamical symmetry is the interacting boson model. Arima and Iachello in 1974 assumed that an even-even nucleus consists of an inert core plus some valence particles. Furthermore, they assume that the valence particles, which are those outside the major closed shells at 50, 82, 126, tend to pair together in states with angular momentum 𝑙=0 𝑠- boson and 𝑙=2 𝑑- boson, and treat these pairs as bosons. The IBM suggested three types of dynamical symmetries, vibrational nuclei (𝔲(5) limit), rotational nuclei (𝔰𝔲(3) limit) and 𝛾-unstable nuclei (𝔬(6) limit). This model has been applied to the Even-Even Uranium and Plutonium Isotopes.
