Abstract
Relative intensities of gamma rays of 156 Gd from the decays of 156 Eu and 156 Tb were measured precisely with a calibrated Ge(Li) detector. Errors of relative intensities for strong gamma rays are about 0.5%. Ratios of reduced E 2-trarnsition probabilities in 156 Gd were deduced from the relative gamma-ray intensities. A perturbation band-mixing treatment was applied for the first excited K π =0 + and K π =2 + rotational bands but the B ( E 2) ratios were not satisfactorily explained.
