(Phys.org)—A team of researchers from several institutions in China has developed a new way to produce neutrons that they claim improves on conventional methods by a factor of 100. In their paper published in the journal ...
Everyone knows that the game of billiards involves balls careening off the sides of a pool table—but few people may know that the same principle applies to fusion reactions. How charged particles like electrons and atomic ...
