Macklin, R L

Using Sb-Be photoneutron socrces (~25 ev), activation cross sections for about fifty nuclides were remeasured and compared with that of iodine. Comparisons with recent fission product poisoning calculations show an average underestimation by a factor of three. The thick spherical shell transmission method was adupted to absorption measurements using flat response neutron detectors. In addition to measuring SbBe photoneutron cross sections for isotopes produeing radioactivity, this method has also been used with V(p,n) neutrons from 5 to 50 kev to measure neutron absorption as a function of energy for the chief fissionable isotopes.
