• Researchers Announce Most Precise Measurement Ever Taken of a Free Neutron's Lifetime

    8 days ago - By ExtremeTech

    To answer the big questions, sometimes we must look to the very small. Researchers at the Los Alamos Neutron Science Center's Ultracold Neutron Source, within Los Alamos National Lab, have been passing the cryo-baton for more than a decade, working at ever colder temperatures in order to study the behavior of neutrons. Now, an international collaboration of scientists has announced the most precise measurement ever taken of a free neutron's lifetime, within an uncertainty of less than two tenths of a percent. Neutrons are the simplest particle that is radioactive, which is to say that they...
