Recent Total Neutron Yield Measurements
The report summarizes results obtained since September, 1951, by total neutron yield experiments using 190 Mev deuterons and the MnSo4 tank method (UCRL-1375 and UCRL-1480). A new method of beam monitoring has resulted in establishing firmly the absolute yield for solid uranium and thorium primary targets backed by a solid uranium secondary. The beam monitoring was done by using a primary target built into a faraday cup. This method circumvents errors caused by recombination in the ionization chambers used previously.

The Chelate Process, IV. Process Flow Involving o-Dichlorobenzene as the Solvent for TTA
Comparative studies of a series of halogenated solvents, as carriers for TTA in the chelate process for plutonium extraction, indicate that ortho-dichlorobenzene most nearly satisfies the requirements that are set forth. A complete process design is presented for use with this solvent, and flow data and equipment capacities are given for dissolver solution and for uranium-free fission product solution as alternate feeds to the process.

The Effect of Gases on the Wetting of Steels by Liquid Bismuth
The effect of air, nitrogen, helium, argon, and a mixture of twenty volume percent of hydrogen in argon on the wetting of a stainless steel (Type 446), a two percent chromium-one half percent molybdenum type steel, and a plain carbon type steel by liquid bismuth was investigated

Photonuclear Stars in Emulsions
Ilford type C-2 nuclear research emulsions were exposed in the x-ray beam from the Berkeley synchrotron at four synchrotron energies. The relative yields of the photo-produced nuclear stars were determined as a function of synchrotron energy and prong number.
