Capture Reaction

Ce144 has been produced by the successive neutron capture reaction Ce142 (n, γ)Ce143(n, γ)Ce144. The pile neutron capture cross section of the 33 hr. Ce143 was determined by separating Pr144, the daughter of Ce144, from the rigorously-purified cerium at frequent intervals. The amount of Pr144 formed increased linearly with the square of the neutron flux in a manner consistent with that of a successive neutron capture reaction. The value for the pile neutron capture cross section of Ce143 was found to be 6.0 ± 0.7 barns.

The half-life of 155Eu has been measured to be 4.65 ± 0.20 years and the absorption cross section has been found to be 4040 ± 125 b by a depletion method using a Ge(Li) detector. The sample of 155Eu was irradiated in the NRU pneumatic carrier where the flux has a small epithermal component. These values are very different from values of [Formula: see text] years and σ ~ 13 000 b reported previously.

The effective neutron capture cross section,[Formula: see text]; the 2200 meters/sec neutron capture cross section, σ0, and the resonance capture integral, RI, of Pr-143 have been measured by an activation method. The values are: [Formula: see text], σ0 = 89 ± 10, and RI = 190 ± 25 barns respectively. The neutron fluxes have been measured with cobalt monitors. All these values have been calculated according to the Westcott convention, which has been outlined insofar as it can be applied to activation work.

The thermal neutron capture cross sections of Na23 and Mn55 have been determined using the activation method. The values are 0.53 ± 0.03 and 12.7 ± 0.3 barns respectively with respect to σAul97 = 93 barns. These agree well with recent pile oscillator results. The half-life for Mn56 is found to be 2.576 ± 0.002 hr.
