The relative yields of the isotopes of cesium, cerium, neodymium, and samarium produced by the thermal neutron fission of Pu239 have been determined with a mass spectrometer. Preliminary values of the absolute yields of 16 isotopes of these elements together with four yields of the xenon isotopes have been assigned by means of isotope dilution techniques.

The absolute fission yield of Ba140 in the thermal neutron fission of U235 has been determined to be (6.32 ± 0.24)%. The reaction B10(n, α)Li7 was used as a neutron monitor and the B10/B11 ratio determined mass spectrometrically before and after neutron bombardment. The Ba140 disintegration rate was determined using 4π counting techniques. The half-life of La140 has been found to be 40.31 ± 0.06 hr.

Mass Spectrometric Techniques

The relative cumulative yields for isotopes of the elements krypton, strontium, xenon, cesium, cerium, and neodymium formed in the thermal-neutron fission of 229Th have been determined by mass spectrometric techniques. Normalization of the relative yields by means of the isotope dilution and isobaric techniques has allowed estimates to be made of the absolute cumulative yields of the heavy-mass group by forcing the sum of the yields to total 100%.

Fission Yields

The absolute fission yields of 22 nuclides formed in the thermal neutron fission of U233 have been measured radiochemically. Disintegration rates were measured by 4π β-proportional counting techniques. The identity of each nuclide was established by chemical separations and decay characteristics as determined by 4π β-counting and γ-ray scintillation spectrometry. The reaction Co59(n, γ)Co60 was used as a neutron flux monitor. Yields were calculated on the basis of [Formula: see text]
