Researchers home in on extremely rare nuclear process

A hypothetical nuclear process known as neutrinoless double beta decay ought to be among the least likely events in the universe. Now the international EXO-200 collaboration, which includes researchers from the Department of Energy’s SLAC National Accelerator Laboratory, has determined just how unlikely it is: In a given volume of a certain xenon isotope, it would take more than 35 trillion trillion years for half of its nuclei to decay through this process – an eternity compared to the age of the universe, which is “only” 13 billion years old.

First report of superconductivity in a nickel oxide material

Scientists at SLAC and Stanford have made the first nickel oxide material that shows clear signs of superconductivity – the ability to transmit electrical current with no loss. The first in a potential new family of unconventional superconductors, its similarity to the cuprates raises hopes that it can be made to superconduct at relatively high temperatures.
