(Phys.org) —The process of molecular hydrogen formation is a key factor in astrophysics – specifically in the physics and chemistry of interstellar clouds. An electrically neutral atom containing a single positively charged ...
(Phys.org)—An international team of astronomers has uncovered molecular and atomic gas clouds associated with the superbubble known as 30 Doradus C, which is located in the Large Magellanic Cloud (LMC). The findings were ...
A team of researchers at the Weizmann Institute of Science in Israel has found a new way to manipulate atoms using light. In their paper published in Physical Review Letters, the team describes the new technique and possible ...
A team of experimental and theoretical physicists from the University of Stuttgart studied a single micrometer sized atom. This atom contains tens of thousands of normal atoms in its electron orbital. These results have been ...
