The first method involves colliding a negatively charged muon and a muonium atom made up of a positive muon and an electron.
20 years ago scientists postulated that other molecules had to be involved: positively charged cyclic hydrocarbon molecules in which five to six carbon atoms are bonded together, also known as cyclic carbenium ions.
The team used a novel technique that involves replacing the electrons in hydrogen atoms with negatively charged particles called muons, and then measuring subtle shifts in the energy that is required to bump a muon into a higher - energy orbit around the single - proton nucleus.
«Our approach provides atom - by - atom control of the size and electron - by - electron control of the charge state of metal clusters on surfaces,» said Dr. Grant Johnson, a physical chemist involved in the study and former Linus Pauling Fellow who recently joined the Laboratory as a full - time scientist.
Producing commercially relevant quantities involves the reduction in solution of positively charged metal ions to neutral atoms in the presence of organic molecules called ligands, which arrest the growth at a particular number of metal atoms.
