Abstract
The E0, M1 and E2 matrix elements were obtained for the interband transitions between levels with spins up to 6 in the beta-vibrational and the ground-state bands of 174Hf by studying the following nuclear reactions: 174Hf(α, α') 174Hf, 175Lu(p, 2nγ) 174Hf, 172Yb(α, 2nγ) 174Hf and 172Yb(α, 2ne) 174Hf. The interband E2 transition matrix elements are well explained in terms of a coupling of the beta vibration with the rotation. The ratios of the E0 to E2 matrix elements for interband transitions between states of the same spin are fairly constant over spins I = 0–6. On the other hand, the M1 to E2 ratios for these transitions increase rapidly with the increase of spin. The observed transition matrix elements are discussed in the framework of the collective model including the rotation-vibration interaction.
