The following report calculates how many neutrons are produced by the O-16([alpha]-n) reaction in a thin and uniform polonium oxide layer.

This progress report discusses activities at Hanford Engineer Works for the month of July, 1944. The organization size increased rapidly in July, jumping from 1384 to 1886, an increase of 502 employees. Shortages existed on special lines such as electricians, instrument mechanics, and power operators. The opportunities to interview and employ Construction personnel improved as the Construction, organization moved past its peak employment figure. 269 houses were completed in Richland and 370 occupancies were reported, reducing the backlog of empty houses due to slow furniture movements. A total of 1530 houses or 35.6% of the village is now occupied. The overall canning yield increased from 63% to 75% while production leveled off at approximately two-thirds of design capacity. The metal machining operation and the test pile operated on a one shift-six day per week basis. The portion of the 100-B Area from the pump house through the filter plant and including the Power House was taken over by Operations on July 25. The Power House in the 200-W Area was started and flushing of process lines with water and steam got under way in the canyon. A new department was formed to control the Protection activities of the plant.

From abstract: "The report describes the complete structure of barium hydrogen phosphate, Ba HPO4, as determined by means of x-ray diffraction. The crystal is orthorhombic, with cell dimensions given by a=5.71 A b=7.05 A c=4.61 A. The calculated density is 4.15gm/cm[^]3 for two molecules in the unit cell. The space group is C[subscript]2v[superscript]7-pmn. The barium, phosphorus, and two sets of oxygen lie in the plane of symmetry. The third set of oxygens are in general positions. Parameters for these atoms have been found, and interatomic distances calculated. The positions of the hydrogens are indicated by the characteristics O-H-O distance (2.58A) between two oxygens."
