Abstract

The Interacting Boson Hamiltonian (IBA-2) to reproduce energy spectrum of isotones is tested The calculated ratio has been  suggested that these nuclei are part of O(6) group symmetry. Reduced electric quadruple transitions between states of  and magnetic dipole between states of , are calculated. The mixing ratios  for transitions between  are evaluated as well. All the calculated results have been  compared with available experimental data and satisfactory results are obtained.

Keywords:Interacting boson model (IBA-2), even – even( 144Ba,146Ce,148Nd), quadruple moments, mixing ratios, energy levels
