Abstract
-ray measurements have been made of the reaction at the Livermore pool-type reactor. Singles spectra were taken with Ge(Li)-NaI(Tl) Compton-suppression and pair-coincidence spectrometers. A total of 280 observed rays were attributed to capture in . Ge(Li)-Ge(Li) coincidence measurements using a three-parameter analyzer system () were analyzed, resulting in the assignment of 129 of the observed transitions to 45 inferred levels in . Comparison of strengths with () strengths leading to the same final states yields a positive correlation coefficient of 0.63. The neutron binding energy is determined to be 11 131.6 ± 0.7 keV.
