Penetration of Heavy Charged Particles in Matter

Edwin A. Uehling1954-12-01Annual Review of Nuclear Science

Following a major shortage of 99Mo in the 2009–2010 period, concern grew that the aging reactor production facilities needed to be replaced. Most producers were using highly enriched 235U (HEU) as the target material. The Organisation for Economic Co-...Read More

The determination of the crystal structure of the σ phase in the iron–chromium and iron–molybdenum systems

G. Bergman、D. P. Shoemaker1954-12-01Acta Crystallographica

slight spread, but there would not be spherical smoothing to the same extent as in the 5 and 10 A reflexions, which are more numerous and at lower angles. The 1.5/t~ reflexion is, therefore, of considerable significance in deciding between a chain structure and a threedimensional net, and it is more profitable to stud…
