Twenty-five new measurements of Kβ/Kα X-ray intensity ratios for elements in the atomic number range 20 to 30 confirm other recent evidence that the variation with atomic number in this region is much less than previously thought, but there is still some disagreement for atomic numbers ...

1 of 2 Nuclear fissionThe impact of a slow (low-energy) neutron splitting the nucleus of the uranium isotope U-235 into two new nuclei. These can be nuclei of any of 30 or more elements ranging in atomic number from 30 to 64. Krypton and barium are examples. Energy and neutrons (2 ...
Defect printability studies have been carried out using low atomic number particles mounted on thin silicon membranes. Transfer of the particle image to a resist-coated wafer was accomplished using synchrotron radiation from the VUV electron storage ring at Brookhaven National Laboratory and subsequent re...
but I'm between cell phones at the moment, waiting for a new one (which arrived today via FedEx when I wasn't home, drat!). Why is it that even if I'm smart enough to establish a mitigation plan for disaster, the correct number of multiple things that then need to go wrong at ...
