By using chemically pure Ho/sup 165/ and enriched isotopes of Nd/sup 146/ and Sm/sup 152/ high-activity sampies of Ho/sup 166/, Nd/sup 147/ and Sm/sup 153/ were mnde by neutron capture. Studies of the strong sources by both magnetic and scintillation spectrometers showed the existence of some gamma rays not previously reported, yielded more exact energy values for the low-energy gamma rays, and made possible better resolulion of the components of the beta spectra. In Ho/sup 166/, gamma rays occur at 80.25, 970, gies are 1839, 1756, 869, 412, and 230 kev. Nd/sup 147/ yields gamma rays at 91.3, 120.6, 198.2, 277, 321, 400, 441, 533, and 688 kev, with beta components at 812, 380, and 230 kev. In Sm/sup 153/ gamma rays are found at 69.8. 103.5, 173.6, and 540 kev and beta components at 812, 380, and 640 kev. A level scheme in agreement with the observed data is presented for each nucleus.
