Özet

In this study, the properties of collective 1?K = 1+0 states in doubly even deformed 168Er and 176Hf nuclei is investigated in the framework of the Random-Phase Approximation (RPA). Spin-spin interactions have shown that the spectroscopic 1+ states (up to energies on the order of 4 MeV) are weakly correlated and are characterized by small values of B(M1). The collective 1+ states with the largest values of B(M1) are expected in the region of energies 9- 11 MeV (K=0). The structure of the 1+0 excitations and the dipole sum rule for M1 transitions are investigated.
