Abstract
The isotopic abundances of the elements xenon, krypton, and cesium formed in the 14-MeV neutron fission of 238U have been measured mass spectrometrically. The relative yields of some isotopes of krypton, strontium, zirconium, molybdenum, ruthenium, iodine, xenon, barium, cerium, and neodymium were measured using a Ge(Li) detector. The ratios were normalized through isobaric nuclides, and absolute yields were obtained by normalizing the sum of the heavy-mass yields to 100%.The results indicate that the fine structure persists at this excitation energy. In particular, the peak at A = 134 which is so characteristic of thermal fission is still prominent in 14-MeV fission.
