THE DECAY SCHEME OF Eu$sup 14$$sup 7$ (in Russian)
A two-channel scintillation spectrometer with faat-slow coincidence scheme (resolving power 5 x 10/sup -8/ sec) was used in the investigations of gamma - gamma coincidence and angular anisetropy of cascade gamma transition for Eu/sup 147/. The europium fraction chromatographically separated from the tantalum targt was kept for 3O days in order to reduce the activities of Eu/sup 146/ and Eu/sup 145/(T = 5 days); the prese nce of Eu/sup 148/ and Eu/sup 149/(T = 50 days) strongly interfered with the experiments. Cascades of gamma transitions, 76--200--600, coincidences (with an energy of approximately 40 kev) with weak gamma rays were also measured. Spectra of Eu/sup 147/ gamma -ray coincidences with 40-kev x rays, the gamma -rays spectra of Eu/sup 147/ (weak region), and strong-region coincidences with 76- and 120-kev gamma rays are plotted, ard a decay scheme for Eu/sup 147/ is plotted on the hasis of the obtained data.
