Gamma-rays in the β-decay of {sup 147}La and {sup 145}Ba were measured using a 4π clover detector to identify high-energy excited levels and γ-rays. In order to determine γ-ray intensities, an efficiency calibration was carried out using single and multiple γ-ray emitters. Applying appropriate coincidence summing corrections, the peak efficiency was experimentally determined from 50 to 3200 keV with 3% accuracy. Through analyses of sum peaks and cascade relations of γ-rays, we newly identified 170 levels between 924 and 3568 keV, and more than 930 γ-rays in the decay of {sup 147}La, and 70 levels between 973 and 3703 keV, and 250 γ-rays in the decay of {sup 145}Ba.
