Description

A laminated scintillator was constructed of Ag activated ZnS in fused B/ sub 2/O/sub 3/. The efficiency of this scintillator was determined and compared with other scintillators. J-values of O for the 41.5 and 44.5 ev and 1 for the 52.6 ev resonances in Pu/sup 239/ were determined. New cross section values are reported for U/sup 235/. Additional attempts to establish fission product mass distribution as a function of neutron energy are reported. A method of analyzing neutron resonances by using partial areas rather than the total area is described. Experiments were conducted to study the fission yield from U/sup ... continued below

Description

A laminated scintillator was constructed of Ag activated ZnS in fused B/ sub 2/O/sub 3/. The efficiency of this scintillator was determined and compared with other scintillators. J-values of O for the 41.5 and 44.5 ev and 1 for the 52.6 ev resonances in Pu/sup 239/ were determined. New cross section values are reported for U/sup 235/. Additional attempts to establish fission product mass distribution as a function of neutron energy are reported. A method of analyzing neutron resonances by using partial areas rather than the total area is described. Experiments were conducted to study the fission yield from U/sup 235/ using resonance neutrons in the range 1 to 10 ev. Fission product analyses were compared with an analysis of pile irradiated U/sup 235/. No differences in fission yields were detected in the range studied. Modifications in the Van de Graaff charging system were made in an attempt to improve charging efficiency and belt life. Angular distributions of neutrons from the reactions nd 1310 kev states. Measured angular distributions from the reaction Li ( alpha , gamma )B/ sup 10/ were compared with theoretical distributions. The observed resonances, gamma rays, and angular-distribution coefficients are reported. Additional data are reported on the decay schemes of Sn/sup 123/, Fe/sup 52/, and Eu/sup 152/. Proton strength function measurements indicate a maximum at A approximately 75. A complete list of the resonance encrgies of Al/sup 27/ and corresponding energy levels in A/sup 28/ was prepared. A polarized neutron beam from the Argonne Research Reactor was used to observe the beta decay of neutrons parallel and antiparallel to their spins. The ratio 0.62 plus or minus 0.10 was determined. Positron polarization and annihilation was investigated in Co, Fe, Ni, Cu, and Gd. The relative light outputs of liquid scintillators using toluene and isopropylbiphenyl solvents and p-terphenyl, diphenyloxazole, and phenylbiphenylyl- oxadiazole were determined. Higher efficiencies were obtained with the isopropylbiphenyl scintillators. Mass spectrometer techniques were used to study the vaporization of BeO, UO/sub 2/, and probability of the heterogeneous reactor to those of a homogeneous reactor of the same dimensions.
