Mixed symmetry states and isospin excitation in N = Z nucleus 52 Fe

The interacting boson model with isospin (IBM-3) was applied to study the band structure and electromagnetic transition properties of the low-lying states in the even-even N = Z nucleus 52 Fe. The isospin excitation states with T = 0, 1 and 2 were identified, and compared with the available data. The study shows that the 2 3 + state is the lowest mixed symmetry state in 52 Fe. The excitation energy of the second 0 2 + state with T = 0 in nucleus 52 Fe was identified. The model calculations with the data show a reasonably good agreement.
