ON THE LEVEL SCHEME OF Eu$sup 15$$sup 3$

The decay scheme of Sm/sup 1//sup 5//sup 3/ (T1/2 = 47 hours) obtained in the (n, gamma )-reaction was investigated. The gamma -transition types were determined for transitions with energies of 69.7 kev (96.4% M1 + 3.6% E2); 83.4 kev (60% M1 + 40% E2); 103.2 kev (98.5% M1 + 1.5% E2) and 98 kev (M1). The 98 kev transition has been observed for the first time. The experimental results are compared with the theory. Some new details of the level scheme of Eu/sup 1// sup 5//sup 3/ are presented.
