Isospin and mixed symmetry structure in 24Mg

  • The interacting boson model with isospin (IBM-3) has been used to study the isospin excitation states and electromagnetic transitions for 24Mg nucleus. The mixed symmetry states at low spin are also analyzed. The theoretical calculations are in agreement with experimental data. The present calculations indicate that the 31+ state is the lowest mixed symmetry state.

Abstract: 

The interacting boson model with isospin (IBM-3) has been used to study the isospin excitation states and electromagnetic transitions for 24Mg nucleus. The mixed symmetry states at low spin are also analyzed. The theoretical calculations are in agreement with experimental data. The present calculations indicate that the 31+ state is the lowest mixed symmetry state.
