摘要：Nuclear structure of 156,158 Dy isotopes have been studied in the frame work of the interacting boson approximation model (IBM-1). The contour plot of the potential energy surfaces, V(?,?), shows that the nucleus 156 Dy is deformed and has transitional characters between SU(3) and O(6) limits, and the nucleus 158 Dy is deformed and has rotational characters, SU(3). Levels energy spectra belonging to the g,?,? bands, electromagnetic transition rates B(E2), electric quadrupole moment (Q) are calculated. The calculated values are compared with the available theoretical and experimental data and show reasonable agreement.
