CAPTURE-GAMMA-RAY SPECTRUM OF Cd$sup 113$ (n,$gamma$)Cd$sup 114$ AND THE ASSOCIATED ENERGY LEVELS IN Cd$sup 11$$sup 4$
The capture gamma-ray spectrum of Cd/sup 113/(n, gamma )Cd/sup 114/ was investigated with the Argonne 7.7-m bent-crystal spectrometer. The observed spectrum consisted of 119 gamma rays with energies below 2 mev. These precision energy measurements were combined with a series of coincidence experiments to modify and extend the level scheme of Cd/sup 114/ The errors in the energy values of five previously observed levels are reduced by a factor of 10. Their new values are found to be 557.8 plus or minus 0.1, 1208.4 = 0.2, 1282.2 = 0.2, 1304.9 plus or minus 0.3, and 1362.9 = 0.3 kev. Five new levels are established at 1133.1 plus or minus 0.2, 1730.3 plus or minus 0.2, 1839.9 = 0.3, 1958.3 = 0.3, and 2202.4 plus or minus 0.3 Mev. Eight more levels are suggested at 1607.8 plus or minus 0.3, 2048.3 plus or minus 0.4, 2225.1 plus or minus 0.4, 2392.5 = 0.4, 2573.8 plus or minus 0.5, 2868.0 plus or minus 0.7, 3216.8; 0.8, and 3484.7 plus or minus 0.8 kev. The limits placed on the spins and parities of these levels by the observed capture gamma rays are discussed. (auth)
