Exploring Intruder Levels of Nuclei (96Zr, 98Zr, 98MO) Within the Framework of IBM-2 Model

Abstract

Current work includes a study of the very rare case called intruder nuclear levels, where there are only seven nuclei in nature. Such cases occur when the first excited state is . The current study included only three nuclei: . The nuclear model used to explore and investigate nuclei in this work is the second interacting boson. The experimental data and theoretical values obtained were in good agreement, indicating this model's success in calculating such anomalies. The main reason for the presence of these levels in other than their natural locations expected according to the IBM model is that they have a double subshell closure. The values of the electric quadrupole transitions, magnetic dipole transitions and zero transitions estimated were in acceptable agreement with experimental data.
