Short-period gamma radiation from PrO/sub 4/, Sm/sub 2/O/sub 3/, and Gd /sub 2 /O/sub 3/ samples irradiated with 20.8-Mev protons was detected. The radiation is found to be due to decay of isomer states of nuclei produced in the nuclear reactions Pr/sup 141/(p,2n)Nd/sup 140m/, Sm/sup 147/(p,2n)Eu/sup 146m/, and Gd/sup 160/(p,p2n)Gd//sup 158m/. The isomer activity previously produced by irradiating a Nd/sub 2/O/sub 3/ sample with protons is identified. This short- lived gamma -radiation is due to decay of the Pm/sup 141m/ produced in the reaction Nd/sup 142/(p,2n)Pm/sup 141m/. (auth)
